Potential and Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy (PE) is the stored energy 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 (KE) is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

How does mass affect Kinetic Energy?

Back

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

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to air resistance.

Front

What is an example of Potential Energy?

Back

A stretched rubber band has potential energy because it is in a position that can cause it to move when released.

Front

What is an example of Kinetic Energy?

Back

A moving car has kinetic energy because it is in motion.

Front

Where is Kinetic Energy maximum on a roller coaster?

Back

Kinetic Energy is maximum at the bottom of a big hill on a roller coaster.

Front

What type of energy is stored in a compressed spring?

Back

A compressed spring stores elastic potential energy.

Front

What is the relationship between Potential Energy and height?

Back

Potential Energy increases with height. The higher an object is, the more potential energy it has.

Front

What is the formula for calculating Potential Energy?

Back

Potential Energy (PE) can be calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
