Potential and Kinetic Energy Background
Potential energy is stored energy. Often, the energy is stored due to an object’s position, such as its position above the ground. The amount of potential energy depends on the height of the object above the ground. The amount of potential energy also depends on the mass of the object.
Kinetic energy is energy of motion. Objects in motion have kinetic energy. Kinetic energy depends on how fast the object is moving. Kinetic energy also depends on the mass of the object.
When an object is up high, it has potential energy. If it falls or rolls downward, its potential energy is converted to kinetic energy as it falls or rolls downward. As its kinetic energy increases, its speed increases.
Imagine a ball rolls down a hill. Its potential energy decreases, and its kinetic energy increases.
Now imagine that ball hits a plastic cup at the bottom of the hill. The ball’s kinetic energy can be used to move that cup. The more kinetic energy the ball has, the more it can move the cup it hits at the bottom of the hill.

Increasing the object's height above the ground will increase its potential energy, while decreasing the object's height will decrease its potential energy. Similarly, increasing the object's mass will increase its potential energy, while decreasing the object's mass will decrease its potential energy.

Increase or decrease
_______ speed will increase kinetic energy. _________ mass will increase kinetic energy. _________ speed will decrease kinetic energy. __________ mass will decrease kinetic energy.
Increasing the speed of a moving object will increase its kinetic energy. Increasing the mass of the object will also increase its kinetic energy. On the other hand, decreasing the speed of the object will decrease its kinetic energy, and decreasing the mass of the object will also decrease its kinetic energy.
