Why does the earth orbit the sun for 1 month

Ametal ball with a mass of 0.028 kg is dropped from rest at a height of 1.0 meters above the ground. assuming the energy in the ball is conserved, how much kinetic energy will the ball have when it is 0.5 meters above the ground?

The ability to make things happen is also called a. heat b. force c. matter d. energy

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.
