Velocity Kitten

This video is a, in a sense, non-constant-velocity example. In order to have constant velocity, one much have both a constant speed and a straight direction. In this video, the kitten (as well as the lizards) do not noticeably maintain a constant speed, or direction, meaning not constant velocity. The kitten jumps around, both changing direction and speed, and the lizards seem to walk with a curved/unspecific direction. This video does, however, show acceleration. Acceleration is the change in speed/velocity over a period of time. The kitten will go from standing still, to running around fast, to standing still again. It shows acceleration, though it may not be very constant.
