Work Step by Step

The Law of Conservation of Energy states that energy can be converted from one form to another, but the total quantity of energy is not changed. This means the energy content of the universe is constant; no energy is created or destroyed. Kinetic energy is the energy of motion. It depends on speed and mass. The heavier and faster the object in motion is, the more kinetic energy it has. Potential energy can be defined as stored energy due to position. A good example of this is water stored behind a dam. It has potential energy that can be converted to electrical energy. The higher the position of the reservoir is, the more potential energy it has. Also, the larger the mass of the water, the more potential energy it has.
