Centripetal Force Scale

Topics: Rotational Motion - Centrifugal Force, Centripetal Force

Equipment: Rod with scale attached, string looped around the hook of the scale with a ball at the end.

Setup: Support the ball so that the scale reads zero. Then drop the ball and see that the scale reacted to the weight. In a large room with no object or person nearby, spin in a circle and watch the reading on the scale, which should increase as you spin faster.

Location: Shelf B-e2


Keywords: Rotate, Ball, Pull, Analog
