On the other hand, suppose your teacher tells you "A bag of gold is located outside the classroom. The displacement required to find the bag of gold has not been fully described. To find it, displace yourself 20 meters." This statement may provide yourself enough information to pique your interest yet, there is not enough information included in the statement to find the bag of gold. For example, suppose your teacher tells you "A bag of gold is located outside the classroom.
Each of these quantities are unique in that a full description of the quantity demands that both a magnitude and a direction are listed. The emphasis of this unit is to understand some fundamentals about vectors and to apply the fundamentals in order to understand motion and forces that occur in two dimensions.Įxamples of vector quantities that have been previously discussed include displacement, velocity, acceleration, and force. On the other hand, a scalar quantity is a quantity that is fully described by its magnitude. A vector quantity is a quantity that is fully described by both magnitude and direction. All these quantities can by divided into two categories - vectors and scalars. Examples of such quantities include distance, displacement, speed, velocity, acceleration, force, mass, momentum, energy, work, power, etc. If you do this for a living, I can't recommend this highly enough.A study of motion will involve the introduction of a variety of quantities that are used to describe the physical world. There is also an online option that's subscription based which is more affordable. But I'm just nitpicking here :)Īlso the pricing is a bit steep. While the interface is nice and easy enough to use, it could have been better if it had native OSX controls and integration. I would have rated this a 5 star app except for the fact that it's based on Flash. Vector magic outputs excellent results regardless of whatever you throw at it. The wizard walks you through a couple of simple steps where you specify image quality, number of colors etc. Perhaps the best attribute is that I rarely have to spend time tweaking parameters all day like I used to with Illustrator, Corel Draw, Inkscape and others. Personally I use the basic mode which works very well even with the most difficult bitmaps. There are 3 modes: automatic, basic, and expert. Secondly, it has 3 modes of usage that makes it simple to use, but also offers expert control. There are a couple aspects that make this the best: first, the results are clean and accurate. Vector Magic blows every other tracing app out of the water. Super-convenient drag-and-drop interface.Powerful preview to inspect the result in detail.Advanced vectorization mode, with fine-grained control.Basic vectorization mode, with easy-to-choose settings.Here are some key features of "Vector Magic": If you've used other tracing tools, you have probably noticed that they have tons of confusing options and settings, and require you to more or less randomly try different combinations of these in the frustrating search for a passable result. Easier user interface with less trial-and-error Normally you'd have to spend a lot of time cleaning up the output from an auto-tracer - with Vector Magic you can oftentimes use the result right away, and if it requires cleanup then it's usually much less than what's required for the results from the competing tools. Vector Magic's results have less noise, while still extracting more detail from the bitmap original. Finer details in the shapes are recovered, and the curves are more faithful to the bitmap original. If you compare results from other tools side-by-side with those from Vector Magic, you will notice that Vector Magic produces vectors that more closely resemble the input image. Why not let Vector Magic do all the work so you can be able to focus your energy on better things? Better accuracy Hand tracing can take you hours per image and is a very tedious task. The shapes are precise mathematical descriptions of the image and can be scaled without becoming blurry or "pixelated" (that blocky look that bitmap/raster images so often get when scaled up). Vector images are images described by shapes such as circles and squares, as opposed to bitmap images which are described by pixels - squares of color arranged in a grid.
Vector Magic converts bitmap images like JPEGs, GIFs and PNGs to the crisp, clean, scalable vector art of EPS, SVG, and PDF with the world's best auto-tracing software.
