Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object that is in motion. It depends on the mass of the object and its velocity.

Front

What is Potential Energy?

Back

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

Front

Give an example of an object with Potential Energy.

Back

A cup sitting on the edge of a table has Potential Energy because of its height above the ground.

Front

Give an example of an object with Kinetic Energy.

Back

A frog jumping into a puddle of water has Kinetic Energy because it is in motion.

Front

What happens to Potential Energy when an object falls?

Back

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

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy is affected by the mass of the object and the square of its velocity (KE = 1/2 mv²).

Front

What is gravitational Potential Energy?

Back

Gravitational Potential Energy is the Potential Energy an object has due to its height above the ground.

Front

How can you increase the Potential Energy of an object?

Back

You can increase the Potential Energy of an object by raising its height or changing its position.

Front

What is the relationship between Kinetic and Potential Energy?

Back

Kinetic and Potential Energy can be transformed into each other; for example, when an object falls, Potential Energy converts to Kinetic Energy.

Front

What is an example of Kinetic Energy in everyday life?

Back

A girl pulling a wagon down the street is an example of Kinetic Energy in action.
