Potential and Kinetic Energy Review

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy stored in an object as it is raised above the ground.

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 formula for Kinetic Energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for Gravitational Potential Energy?

Back

Gravitational Potential Energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

How does height affect Gravitational Potential Energy?

Back

The higher an object is, the more Gravitational Potential Energy it has.

Front

How does speed affect Kinetic Energy?

Back

The faster an object moves, the more Kinetic Energy it has, since it is proportional to the square of its speed.

Front

What happens to Potential Energy when an object falls?

Back

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

Front

Can an object have both Kinetic and Potential Energy at the same time?

Back

Yes, an object can have both types of energy, such as a roller coaster at the top of a hill (Potential) that is about to descend (Kinetic).
