Free fall #1

The free fall experiment of Galileo (1564 - 1642) revealed the uniform acceleration of a ball as it falls. A ball is released at zero velocity at the top of a tower. A stroboscope illuminates the ball’s motions at uniform time intervals when you select "stroboscopy". You have a cursor to measure the ball’s position at various time intervals, and you just need to rollover each  image of the ball  to display the time interval involved. The Print Button enables you to make a hard copy of the screen.
