Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a rock at the top of a hill has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

Where is potential energy maximum on a roller coaster?

Back

At the top of a big hill.

Front

What happens to kinetic energy when an object speeds up?

Back

The kinetic energy increases.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 m v², where m is mass and v is velocity.

Front

Can energy be created or destroyed?

Back

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

Front

What type of energy is associated with a stretched rubber band?

Back

Potential energy, specifically elastic potential energy.

Front

What type of energy does a moving car have?

Back

Kinetic energy.

Front

If two objects are moving at the same speed, how does mass affect kinetic energy?

Back

The object with greater mass has more kinetic energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.
