Potential and Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object has due to its motion. It depends on the mass of the object and its velocity.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It can be converted into kinetic energy.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy an object possesses because of its height above the ground. It is calculated as weight times height.

Front

How does the speed of an object affect its kinetic energy?

Back

The kinetic energy increases with the square of the speed. If the speed doubles, the kinetic energy increases by four times.

Front

What happens to the kinetic energy of a car as it accelerates?

Back

The kinetic energy of the car increases as it accelerates.

Front

Where is the maximum potential energy on a roller coaster?

Back

The maximum potential energy is at the top of the tallest hill.

Front

Which object has potential energy?

Back

A book on a shelf has potential energy because it is elevated above the ground.

Front

At what position does a rock have the greatest kinetic energy when rolling down a hill?

Back

The rock has the greatest kinetic energy at the bottom of the hill.

Front

What is Elastic Potential Energy?

Back

Elastic Potential Energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What is the relationship between potential energy and kinetic energy in a roller coaster?

Back

As a roller coaster goes down a hill, potential energy is converted into kinetic energy, increasing its speed.
