Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It is often associated with gravitational energy, calculated using the formula PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

How does Kinetic Energy change when an object speeds up?

Back

As an object speeds up, its Kinetic Energy increases because Kinetic Energy is proportional to the square of its velocity.

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 the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.
