What is Kinetic Energy (KE)?

Back

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

Front

What is Gravitational Energy (GE)?

Back

Gravitational Energy is the potential energy held by an object because of its height above the ground. It is dependent on the object's mass and height.

Front

What is Elastic Energy (EE)?

Back

Elastic Energy is the potential energy stored in an object when it is compressed or stretched, such as in springs or rubber bands.

Front

How does energy convert when a ball bounces?

Back

The order of energy conversion is: Gravitational Energy (GE) to Kinetic Energy (KE) to Elastic Energy (EE) to Kinetic Energy (KE) to Gravitational Energy (GE).

Front

Where is the Kinetic Energy greatest on a roller coaster?

Back

The Kinetic Energy is greatest at the lowest point of the roller coaster, where the speed is highest.

Front

Can Kinetic Energy be converted to Gravitational Energy?

Back

Yes, Kinetic Energy can be converted to Gravitational Energy when an object moves upward.

Front

Can Gravitational Energy be converted to Kinetic Energy?

Back

Yes, Gravitational Energy can be converted to Kinetic Energy when an object falls.

Front

What happens to energy in a pendulum swing?

Back

In a pendulum swing, energy converts from Gravitational Energy (GE) to Kinetic Energy (KE) and back to Gravitational Energy (GE).

Front

What is the formula for Kinetic Energy?

Back

The formula for Kinetic Energy is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for Gravitational Energy?

Back

The formula for Gravitational Energy is GE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
