Constant Velocity:

This video demonstrates constant velocity of two small toy cars racing. The two cars are moving at a constant speed and distance; however, the velocity rates are different. One car was able to travel the same distance in a quicker time. Each car moves at a consistent speed throughout the entire video clip, at no point did either of them speed up or slow down

Acceleration:

A clear demonstration of how the acceleration of golf ball changes going down a slope. The ball starts at a rest position and travels down the slant. In the video, you can clearly see the ball spinning faster and rolling down more and more distance each second. The velocity changed over a period of time which demonstrated the acceleration of the golf ball.
