This easy to operate system is designed to demonstrate uniform acceleration due to gravity and its determination and to demonstrate conservation of mechanical energy.
Components:
support (1.80 m height)
electromagnet to hold the ball
2 highly sensitive photoelectric sensors
graduated ruler (1.50m length)
ball receptacle
stable cast 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 starts and stops the clock using the photo cells. Supplied with Digital Timer feature with Electromagnetic Control.
