System to Study Free Fall, Optical Gates
This easy to operate system is designed to demonstrate uniform acceleration due to gravity and its accurate determination and to demonstrate conservation of mechanical energy and for accurate determination of acceleration due to gravity Ã¢â¬ËgÃ¢â¬â¢.
Components: Supports (1.80m height), electromagnet to hold the ball, 2 highly sensitive photo-optical gates, graduated ruler (1.50m length), ball receptacle, stable metal base, 3 screws to adjust the support in the vertical plane.Principle: The electromagnet holds the steel ball at the top of the support. When you press the button on the control box the ball falls down. During the motion the ball triggers the start and stop of the digital chronometer when it crosses upper and lower optical gate respectively. Supplied with chronometer & Electromagnetic Control Box and instruction manual.
