PLEASE HELP ASAP!! To begin your investigation, consider a spring hanging from a fixed point. If a weight were attached to the end of the spring and then released, how would the weight move? If you were attempting to model the motion of the weight, what two variables would you use and what would they represent?

If a heavy object were to be hung on a spring then released, the weight would movedownward. The two variables would be the weight and the force. The force enacted by the weight stretching the spring and the force returning the spring to its original shape is determined by its height the “h” variable.

The two forces repel each other over “t” /time.
