Mechanical energy is the sum of the energy due to motion and the energy due to position of an object or a group of objects that work together. Wind, falling rocks, and moving water all have mechanical energy. A water wheel is an example of an object that uses mechanical energy. The falling water causes the wheel to rotate. The falling water and the rotating wheel have mechanical energy. A bowling ball has mechanical energy. When it strikes the pins, the mechanical energy is transferred to the pins.Gravitational energy is the energy stored in objects that are attracted to each other by the force of gravity. All objects have mass and objects have gravitational energy because of their mass. The greater the mass, the greater the gravitational attraction or gravitational force. If you hold a ball over your head it has gravitational energy. If you drop the ball the gravitational energy will pull the ball back to the Earth.
