Previous Next Drop Lead and Cork Balls # 1C20.15
Description: This demonstration is used to show that the acceleration due to gravity does not depend on the mass of the object. F = G(Mm)/(r*r) = ma. Solving this for acceleration gives: a = GM/(r*r). Instructions: Simultaneously drop a lead ball and cork while standing on the lecture bench or small stool. Hazards: When dropped on one's foot, a lead ball could cause some discomfort. Parts: Cork Lead ball Small stool (if requested) Pizza pan (if requested) Purchased/Built: built Quant. in Demo Room: 1 Demo References Sutton M-80 Iron and wood balls are dropped simultaneously. The Physics Teacher TPT 17(5),314 Hint on how to drop a heavy and light object simultaneously with one hand.
