Detailed explanation-1: -Things like slingshots work by storing energy in elastic materials, such as the rubber bands in this activity. The stored energy is called potential energy.

Detailed explanation-2: -When pulled all the way back, the slingshot stores 180 J of Elastic potential energy. He releases. When the rock is half way out of the slingshot it has 135 J of Kinetic Energy.

Detailed explanation-3: -The energy store in the slingshot while stretching the rubber band of the slingshot is elastic potential energy. This elastic potential energy associated with the work done by the stretching force on the band with the target.

Detailed explanation-4: -When the person holds the slingshot in this position, there is a force acting on the object that is trying to push it away from the person. This force is called kinetic energy.
