Help with Physical Science! I have to do this discussion on potential and kinetic energy. The example of the problem is a 4 pound weight being lifted from the ground on a string. There are also scissors there to cut the string for the 4 pound to drop. The two questions is to explain how the object (the weight on the string) had potential energy. And how the object had kinetic energy. THANK YOU
