Potential and Kinetic Energy BackgroundPotential 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.Question 11. How will changing each property affect the potential energy of an object?(2 points)
Changing the height of an object will directly affect its potential energy. The higher the object is, the greater potential energy it will have. On the other hand, changing the mass of an object will also have an effect on its potential energy. The greater the mass of the object, the greater its potential energy will be.

Changing each property will have the following effects on the potential energy of an object:
1. Increasing the object's height above the ground will increase its potential energy.
2. Decreasing the object's height above the ground will decrease its potential energy.
3. Increasing the object's mass will increase its potential energy.
4. Decreasing the object's mass will decrease its potential energy.
what category do they go under.
The changes in potential energy due to changing the height of an object fall under the category of "potential energy and height."
The changes in potential energy due to changing the mass of an object fall under the category of "potential energy and mass."
