Principle

The aim of this experiment is to film a high-speed video of a sphere falling from the height of fall h. The "measure Dynamics" software is used for the graphical representation of the distance as a function of time t and also as a function of the square of time t^2 as well as the graphical representation of the velocity v and acceleration a as a function of time t. Then, the measured values are used to determine the gravitational acceleration g.
The velocity and acceleration are then integrated into the video, followed by a discussion of the results.
