Figure 2 snows the kinetic energy as a on of timme for a 5 kg object that is released from rest and falls towara Earth S surrace Both objects are released simultaneously from the same height. How much does the gravitational potential energy of the object- object-Earth system change from 0 s to 10 s?

Expert Solution
Step 1
Law of Conservation of Energy
According to the law of conservation of energy, the total energy of an isolated system remains constant. This means the total energy of a system where no external force is applied is a constant.
