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.

Question

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 1
1. How will changing each property affect the potential energy of an object?(2 points)
This will increase the object's potential energy. This will decrease the object's potential energy.
increasing the object's height above the ground

decreasing an object's height above the ground

increasing the object's mass

decreasing the object's mass

Question 2
2. How will changing each property impact the kinetic energy of a moving object?(2 points)
Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse.
Response area speed will increase kinetic energy. Response area mass will increase kinetic energy. Response area speed will decrease kinetic energy. Response area mass will decrease kinetic energy.
