Principle

A steel sphere is launched by a ballistic unit and the resulting trajectory is filmed with the aid of a video camera. The "measure Dynamics" software is used to demonstrate the dependence of the trajectory on the launching angle and on the initial velocity, and to determine the range and height of the trajectory. In addition, the resulting trajectory is integrated into the video, followed by a discussion of the course of the velocity.

Benefits
