Potential & 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 the speed at which it is moving.

Front

How is Potential Energy calculated?

Back

Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

How is Kinetic Energy calculated?

Back

Kinetic Energy (KE) = 1/2 × mass (m) × velocity (v)².

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 is the relationship between speed and Kinetic Energy?

Back

The faster an object moves, the more Kinetic Energy it has.

Front

What is an example of Potential Energy?

Back

A stretched rubber band or a book on a shelf has Potential Energy.

Front

What is an example of Kinetic Energy?

Back

A moving car or a flowing river has Kinetic Energy.

Front

At what point does an object have maximum Potential Energy?

Back

An object has maximum Potential Energy at its highest point.

Front

At what point does an object have maximum Kinetic Energy?

Back

An object has maximum Kinetic Energy at its lowest point or when it is moving the fastest.
