Free fall

Product No: P1199000

Principle

For determining the gravitational acceleration of the Earth (g) using the familiar distance-time relationship for accelerated movement with a falling sphere apparatus. A steel sphere is held in the release mechanism between a pin and a plunger, thereby closing an electrical circuit. When the sphere is released by means of a cable trigger, the electrical contact is interrupted and that starts the electronic counter. The sphere falls onto the receiving tray of the receiver switch, which then stops the counter. Bodies of different mass and surface area fall through air-filled space at different speeds, whereas they fall at the same speed if the air resistance and the buoyancy in air is negligible (free fall).
