Potential vs. Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It is the energy that has the potential to do work.

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 does height affect Potential Energy?

Back

The higher an object is positioned, the more potential energy it has. This is because potential energy is calculated as mass x gravity x height.

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 mechanical energy.

Front

What is the formula for Kinetic Energy?

Back

The formula for Kinetic Energy (KE) is 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 the speed doubles, the kinetic energy increases by four times.

Front

What is an example of Potential Energy?

Back

A drawn bow has potential energy due to the tension in the string and the position of the bow.

Front

What is an example of Kinetic Energy?

Back

A rolling ball has kinetic energy due to its motion.

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 are indicators that an object has energy?

Back

Indicators include light, sound, heat, and motion.
