Document Summary
This experiment is designed to explore the nature of a spring. Therefore we will want to find the accelerating spring and cylinder"s effective mass: meff. This experiment is done with the room lights off. The flashing strobe light, around 400 flashes a minute, and the clicking sound which it makes, may cause one to feel ill. If you have a history of being adversely affected by flashing lights, you may exit the lab while measurements are being made. A body at rest has no net force acting on it, all the forces applied to it sum to zero. We use this principal to measure an unknown force by balancing it with a known one. In this case, we will use the force of gravity acting on a mass of known weight to determine the force exerted by a spring when it is extended away from its neutral position.
