The positions of a bouncing ball at different points in time can be captured with a camera and stroboscope. It is thus possible to determine g, the acceleration due to gravity, using a ball bearing that is rolled off a horizontal surface.
The parabolic motion can be described using the SUVAT equations. If the positions of the ball can be found, they can then be used to analyse the motion of the ball and to calculate an experimental value of g.
