Potential Energy and Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It has the potential to do work when released.

Front

What is Kinetic Energy?

Back

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

Front

Where is potential energy maximum on a roller coaster?

Back

At the top of a big hill.

Front

When does an object have no kinetic energy?

Back

When it's at rest.

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only be transformed from one form to another.

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 Potential Energy?

Back

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

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What type of energy is associated with a stretched spring?

Back

Potential Energy, specifically elastic potential energy.

Front

What type of energy is associated with a moving car?

Back

Kinetic Energy.
