Skid marks from aircraft tires on a runway. A skid mark is the visible mark left by any solid which moves against another, and is an important aspect of trace evidence analysis in forensic science and forensic engineering.
Scratch is a high-level, block-based visual programming language and website aimed primarily at children as an educational tool, with a target audience of ages 8 to 16. [9] [10] Users on the site can create projects on the website using a block-like interface.

The velocity vector of a point A in the wheel is perpendicular to the segment AP and is proportional to the length of this segment. In particular, the velocities of points in the wheel are determined by the angular velocity of the wheel in rotation around P.
Tangential speed is the speed of an object undergoing circular motion, i.e., moving along a circular path. [1] A point on the outside edge of a merry-go-round or turntable travels a greater distance in one complete rotation than a point nearer the center.
If a team says that a task will take four hours or is worth 4 points instead of taking two hours or being worth two points, their velocity will look better (sometimes called point inflation). [5] [1] A second problem with velocity is that it does not take quality, alignment with user goals or priority into account.
The task is to construct a sequence of points that closely follow the points () on the trajectory of the exact solution. Where Euler's method uses the forward difference approximation to the first derivative in differential equations of order one, Verlet integration can be seen as using the central difference approximation to the second derivative:
