Kinetic and Potential Energy

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

What is Potential Energy?

Back

Potential Energy is stored energy based on an object's position or state. It has the potential to be converted into kinetic energy.

Front

How is Kinetic Energy calculated?

Back

Kinetic Energy (KE) is calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between speed and Kinetic Energy?

Back

Kinetic Energy increases with the square of the speed. If speed doubles, kinetic energy increases by four times.

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.

Front

What happens to Potential Energy when an object falls?

Back

As an object falls, its Potential Energy decreases while its Kinetic Energy increases, conserving the total energy.

Front

What is an example of Potential Energy?

Back

A rock held at the top of a hill has Potential Energy due to its height above the ground.

Front

What is an example of Kinetic Energy?

Back

A moving car has Kinetic Energy due to its motion.

Front

How does height affect Potential Energy?

Back

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

Front

What is the formula for Potential Energy?

Back

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