![]() ![]() ![]() We must find their components along the x- and y-axes, too. Of course, to describe motion we must deal with velocity and acceleration, as well as with displacement. However, to simplify the notation, we will simply represent the component vectors as x x and y y.) If we continued this format, we would call displacement s s with components s x s x and s y s y. (Note that in the last section we used the notation A A to represent a vector with components A x A x and A y A y. The magnitudes of these vectors are s, x, and y. Figure 3.34 illustrates the notation for displacement, where s s is defined to be the total displacement and x x and y y are its components along the horizontal and vertical axes, respectively. (This choice of axes is the most sensible, because acceleration due to gravity is vertical-thus, there will be no acceleration along the horizontal axis when air resistance is negligible.) As is customary, we call the horizontal axis the x-axis and the vertical axis the y-axis. The key to analyzing two-dimensional projectile motion is to break it into two motions, one along the horizontal axis and the other along the vertical. This fact was discussed in Kinematics in Two Dimensions: An Introduction, where vertical and horizontal motions were seen to be independent. The most important fact to remember here is that motions along perpendicular axes are independent and thus can be analyzed separately. In this section, we consider two-dimensional projectile motion, such as that of a football or other object for which air resistance is negligible. The motion of falling objects, as covered in Problem-Solving Basics for One-Dimensional Kinematics, is a simple one-dimensional type of projectile motion in which there is no horizontal movement. The object is called a projectile, and its path is called its trajectory. Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. Apply the principle of independence of motion to solve projectile motion problems.Determine the location and velocity of a projectile at different points in its trajectory.Identify and explain the properties of a projectile, such as acceleration due to gravity, range, maximum height, and trajectory.For example, enter the time of flight, distance, and initial height, and watch it do all calculations for you!īe sure also to check the parabola calculator to learn more about such a curve from a mathematical point of view.By the end of this section, you will be able to: Using our projectile motion calculator will surely save you a lot of time. Maximum height: h m a x = V y 2 / ( 2 g ) h_\mathrm = h V^2_ \mathrm y / (2 g) h max = h V y 2 / ( 2 g ).Range of the projectile: R = 2 V x V y / g R = 2 V_\mathrm x V_\mathrm y / g R = 2 V x V y / g. ![]() Time of flight: t = 2 V y / g t = 2 V_\mathrm y / g t = 2 V y / g.Vertical velocity component: V y = V sin α V_\mathrm y = V \sin \alpha V y = V sin α.Horizontal velocity component: V x = V cos α V_\mathrm x = V \cos \alpha V x = V cos α.Launching the object from the ground (initial height h = 0).Uff, that was a lot of calculations! Let's sum that up to form the most essential projectile motion equations: Vertical acceleration is equal to − g -g − g (because only gravity acts on the projectile).Vertical velocity can be expressed as V y − g t V_\mathrm y - g t V y − g t.Horizontal velocity is equal to V x V_\mathrm x V x .Vertical distance from the ground is described by the formula y = h V y t − g t 2 / 2 y = h V_\mathrm y t - g t^2 / 2 y = h V y t − g t 2 /2, where g g g is the gravity acceleration.Horizontal distance traveled can be expressed as x = V x t x = V_\mathrm x t x = V x t where t t t is the time.We tackled both problems in the horizontal projectile motion calculator and free fall calculator, respectively. If, additionally, α = 90°, then it's the case of free fall. If the vertical velocity component is equal to 0, then it's the case of horizontal projectile motion. Three vectors - V V V, V x V_\mathrm x V x and V y V_\mathrm y V y - form a right triangle.The vertical velocity component V y V_\mathrm y V y is equal to V sin α V \sin\alpha V sin α.The horizontal velocity component V x V_\mathrm x V x is equal to V cos α V \cos\alpha V cos α. ![]()

![]() ![]() Since shooting is not a major strength of this build, we’ve opted to go with more of a playmaker build. Our first pick is Precise Passing 2, which boosts Passing by five points. The Dangler archetype doesn’t have great shooting attributes as compared to the Sniper build, but the attributes are more or less fine for scoring nevertheless. Much like with the Sniper build, this Dangler loadout helps maximize Speed and Acceleration, which is necessary when utilizing a player with this archetype. Specialty – Loose Puck Dekes/Stride Dekes/Toe Drag Dekes/Windmill Dekes.Trait Slot 1 – Precise Passing 2/Target Slapper 2.This specialty should help maximize the shoot-first tendencies of a Sniper in the World of CHEL. Our Specialty pick is Quick Release, which gives a slight boost to Wrist Shot Power when performing a Snap Shot. The second slot goes to Cardio Master 2, which boosts Endurance (+5) and Durability (+7), both of which should come in handy. As far as trait slots go, our first pick is Target Slapper 2, which boosts Slap Shot Accuracy by +4 and decreases a useless attribute in Defensive Awareness. However, the Strength and Durability will be quite low, so keep that in mind when skating. This Sniper build has max Speed (90) and Acceleration (90) thanks to the small, 5’7” frame that this player will possess. ![]() But which builds should you look to create in the World of CHEL? Let’s go over some of our recommended loadout builds in NHL 21. Having the right build is important, as creating the ideal player can maximize the most desirable attributes and help give you that extra edge out on the ice. In NHL 21’s World of CHEL, users can customize the look of their avatars, the archetype, attributes, and traits. ![]() ![]() ![]() ![]() Unless you’re staying in the most barebones camper van out there, your RV has a freshwater tank. Allstays has a similar search feature that tends to yield good results also. This should give you a list of results to choose from. To find free camping with Campendium, type in the area you’d like to visit and select Price: “Free” and Hookups: “None”. Knowing these things will help you make an informed decision, helping you avoid driving to a spot only to discover it won’t work for your rig. What size RV might fit in a particular area.Reviews are submitted by other campers, which include important information such as… These websites help you find spots that will work for you, whether you drive a little camper van or pull a gigantic fifth wheel. Instead, we recommend that you research both the developed campground options and dry camping options using Campendium or Allstays. Sure, you could just stick to the developed campgrounds on these lands, but you’d be missing out on some seriously awesome wilderness camping. These are the first places you’ll want to look to find free camping.Īll that said, even knowing that these public lands are full of boondocking spots, it can still be difficult understanding which areas are off limits and which areas will and will not work for your setup. The Bureau of Land Management (BLM), The National Forest Service, and the Fish and Wildlife Service all own plots of land that are full of great camping spots-a far cry from the truck stops many RVers might find themselves dry camping in. There are certain places where dry camping is perfectly legal, but if you camp elsewhere, you’re liable to get yourself into trouble.įortunately, finding those legal boondocking spots isn’t too terribly difficult. The thing about boondocking is, you can’t just set up camp anywhere. ![]() Boondocking is the perfect way to practice your self-sufficiency and prove to the world that you can take care of yourself just fine without the help of an RV park. Be Self-Sufficientįinally, many people like the idea of being completely self-sufficient. Boondocking is a fabulous way to get a break from those high campground costs and instead save your cash for other, more fun things. When you’re living in an RV fulltime, those fees add up quickly. Save MoneyĬamping spots in RV parks are pricey. It also gives you a chance to see places many will never see, and ensures you will always have an absolutely amazing view out your window. Escape Into NatureĪs mentioned before, RVing offers a fabulous opportunity to escape into nature, and boondocking is the very best type of RVing to use for this sort of escape.Ĭamping in the middle of nowhere allows you to take a break from the cramped quarters of a campground or RV park, offering the peace and quiet of nature right outside your door. Some of the most popular reasons are listed below. Why would someone choose to camp without any hookups when there are so many RV parks out there? Well, there are actually several reasons one might make this choice. The boonies might be one of the many national forests, a desert, or even the beach, but is always completely off the grid and never in a parking lot. More specifically, the term refers to dry camping in the wilderness, a.k.a. Dry camping could happen in a Walmart parking lot, a rest area, at truck stops, or anywhere else you can legally park overnight.īoondocking is a type of dry camping. Dry camping is staying one or more nights in a place with no water, sewer, or electric hookups. This is generally free camping, but sometimes will incur a nominal fee. Let’s first address the most basic of boondocking questions: What is boondocking?įor starters, it’s good to know what dry camping is. I have also packed some food and water for our trip. I have a bit of a trouble with my eyes so I have packed my glasses along with my acuvue contact lenses uk for the trip. I had to make sure I have packed everything I needed as we will be gone off the grid for a while. In this article we’re going to discuss the ins and outs of boondocking so you can take full advantage of fulltime RV living by escaping into nature once in a while. This is where boondocking comes into play. Unfortunately, most RV parks and campgrounds don’t really offer the wilderness camping experience, meaning RVers have to seek out these experiences themselves. Off with the phones and all the other distractions of the urban life and enjoying the evening around a small dinner using BestOfMachinery‘s portable butane burners. The good thing about this kind of trip is you leaving all of the things you won’t need to just survive. This article may contain compensated links, please read our disclaimer for more information.Įver wanted to escape from everything, head out into the wilderness, and spend some time reconnecting with nature? Well, one of the many great things about RV living is that you can do just that, anytime you like. ![]() ![]() The documentation (especially the screenshots) is woefully out of date. And the user interface leaves a lot to be desired. I've had it crash on me more than a few times (but it has never lost anything important - another good reason it never writes to original files). LibreOffice, GiMP) it's far from perfect. Of course, as with (most?) big, complex open-source software like this (ex. It has several different plugins for adjusting levels, from a simple brightness/contrast/gamma tool, to a powerful histogram + curve tool. For example, it's got a plugin that will un-warp images based on the camera and lens you used. The editor itself isn't particularly flashy, but it gets the job done and has plenty of powerful plugins baked in. The RAW is always there in case I want to try again. Currently I'm just making versions ad hoc when I feel the edited photo looks "good enough". You can choose if you want it to store a new version after each edit, or only after each edit that can't be completely reversed (for example, a 16->8 bit conversion or a blur operation). The editing tools default to maintaining "versions" of images. Or, I can take a bunch of JPGs straight out of the camera, and do a bulk resize with auto levels, if I just want to quickly publish to Facebook or something.ĭigiKam NEVER changes the original image - it's literally impossible to tell any of the tools to overwrite the original image. then dump out 16-bit PNGs for further editing. So I can take a folder full of RAWs and do a customized export process, adjust color balance and exposure, etc. Includes a very powerful batch processor, that supports multi-processor and can run any of the editing plugins. I haven't found much use for it, but I imagine for a professional photographer that would be important. It includes a light table so you can do side-by-side comparisons of sets of photos. If I've taken bracketed photos, I add "color" to them so they're visually obvious as a group, so I can run them through Luminance HDR later. Currently, I'm using the "flags" to mark the photos that are no good (red), maybe (yellow) and accepted (green). This lets you come up with your own organizational system for your photos. The album organizer lets you assign tags, flags (red/green/yellow), color groups, and "stars" to each image. Having never used Lightroom, I can't say with any authority how well they have done in this pursuit, but for me as a beginner photographer, I find that DigiKam has some VERY powerful features: In other words, I doubt the developers are trying to literally copy Lightroom, but rather want to replicate its functionality in their own tool. It seems to be a Lightroom substitute/clone, in the same way that GiMP is a substitute/clone for Photoshop. I usually create a sub-album of the main one to store the low-resolution exports. Use the batch processor to do a 16->8 bit conversion, resize, and save as JPG. Select the latest versions of all the files I want to upload Full-resolution 16-bit PNG files are not easy to work with, and can't easily be uploaded to Facebook or whatever. DigiKam will only show the most recent version of an image in the tray, but you can flag certain versions to always appear if you want.Įxport for sharing. The downside is that 16-bit PNGs take up a LOT more disk space than a 12-bit RAW and don't compress very well.įor each image that needs extra work, open it in the image editor and do the additional tweaks. ![]() The result is images that usually look pretty close to the camera-generated JPGs that were generated alongside the RAWs. I usually throw in a few minor adjustments to the levels and saturation, since a straight RAW export usually looks muted and dim. Run a batch process to export all the RAWs to 16-bit PNGs (or TIFFs, or whatever you want). ![]() This leaves me with just green and red flagged images. Then only show "yellow" and make final decisions (red/green). I then switch to showing just unflagged pictures (in case I missed any) I have my display filter set to only show yellow, green, and unflagged, so the rejects just disappear from the tray as I flag them. Go through the RAWs and flag each of them red, yellow, or green (ctrl+1,2,3). Here's a general workflow that works for me: So your input files (whether they're RAWs or JPEGs) will always be kept pristine, and your edits always applied to new files.ĮDIT: This page helped me figure out the editor a little better: The screenshots are way out of date, but the basic information is sound. One thing I do like about DigiKam is that it has a hard rule to NEVER overwrite/replace any original file. DigiKam seems to have all the same photo editing features as Darktable, but the interface is a bit more awkward. I looked at Darktable too, and while I like its RAW editor, it wasn't immediately obvious to me how you could use it to organize/tag/process lots of photos in albums. ![]() ![]() ![]() Video Demosĭallas, TX - SeptemTopaz Labs is announcing Topaz Photo AI, which automatically detects and fixes image quality issues with deep learning, allowing photographers to focus on the creative editing process in much less time.

Norways Doomsday Seed Vault Is Getting a 12.7 Million Makeover After Flood. Right now, they are doing all they can to protect the vault. They have also installed pumps into the seed bank in case the past repeats itself. This includes waterproofing the tunnel into the mountain and digging trenches in order to divert the meltwater. With the climate rapidly changing and the permafrost melting, vault managers must now find a way to protect the world’s largest collection of seeds. Though water did get past the vault’s threshold, none of the seeds had been damaged. “It was not in our plans to think that the permafrost would not be there and that it would experience extreme weather like that,” Hege Njaa Aschim, from the Norwegian government that owns the vault, told The Guardian.”It was supposed to without the help of humans, but now we are watching the seed vault 24 hours a day.”Īt the end of last year in Spitsbergen, average temperatures warmed by 7☌ (11☏) above normal. However, the event has raised concern among the community tasked with protecting the seed bank, which is supposed to be a lifeline in case of an environmental emergency. This led to higher-than-usual melting and heavy rains, instead of snowfall.īuried deep inside a sandstone mountain in the Arctic Svalbard archipelago, meltwater gushed into the entrance and subsequently froze. Thankfully, no seeds were lost and the ice has since been hacked out. However, the “impenetrable” fortress easily succumbed to the forces of nature, as recorded heat hit the region. ![]() ![]() “It is a fail-safe seed storage facility, built to stand the test of time – and the challenge of natural or man-made disasters,” reads the website by Crop Trust, the organization tasked with protecting global crop diversity.
