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 and speed of the object.

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 height or condition.

Front

How is Kinetic Energy calculated?

Back

Kinetic Energy (KE) = 1/2 * mass (m) * velocity (v)².

Front

How is Potential Energy calculated?

Back

Potential Energy (PE) = mass (m) * gravity (g) * height (h).

Front

What happens to Kinetic Energy when speed increases?

Back

Increasing an object's speed will increase its Kinetic Energy.

Front

At what point is Potential Energy the greatest in a roller coaster?

Back

Potential Energy is greatest at the highest point of the roller coaster.

Front

What is the relationship between Kinetic Energy and mass?

Back

Kinetic Energy increases with an increase in mass, assuming speed remains constant.

Front

What is the relationship between Potential Energy and height?

Back

Potential Energy increases as the height of an object increases.

Front

What is an example of Kinetic Energy?

Back

A moving car, a running athlete, or a flowing river all possess Kinetic Energy.

Front

What is an example of Potential Energy?

Back

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