Extra Credit Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It is often associated with the height of an object above the ground.

Front

How does height affect Potential Energy?

Back

The higher an object is positioned, the greater its Potential Energy. This is because Potential Energy is calculated as PE = mgh (mass x gravity x height).

Front

At what point does an object have maximum Kinetic Energy when rolling down a hill?

Back

An object has maximum Kinetic Energy at the bottom of the hill, where its speed is greatest.

Front

At what point does an object have maximum Potential Energy when climbing a hill?

Back

An object has maximum Potential Energy at the top of the hill, where it is at its highest point.

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its Potential Energy decreases while its Kinetic Energy increases.

Front

What is the relationship between Kinetic and Potential Energy?

Back

Kinetic and Potential Energy are forms of mechanical energy. As one increases, the other decreases in a closed system, such as a roller coaster.

Front

What is an example of Kinetic Energy in everyday life?

Back

A moving car, a running dog, or a thrown baseball are all examples of Kinetic Energy.

Front

What is an example of Potential Energy in everyday life?

Back

A book on a shelf, a drawn bow, or water stored in a dam are all examples of Potential Energy.

Front

How can you increase the Kinetic Energy of an object?

Back

You can increase the Kinetic Energy of an object by increasing its mass or its speed.
