#12Q Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its 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 the stored energy in an object due to its position or state. It has the potential to do work when released.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy an object has due to its height above the ground. It increases with height.

Front

What is Elastic Potential Energy?

Back

Elastic Potential Energy is the energy stored in elastic materials as the result of their stretching or compressing.

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

How does mass affect Kinetic Energy?

Back

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

Front

How does speed affect Kinetic Energy?

Back

Kinetic Energy increases with the square of the speed. Doubling the speed quadruples the kinetic energy.

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 Kinetic Energy?

Back

A tennis ball rolling across the court is an example of Kinetic Energy.

Front

What is an example of Potential Energy?

Back

The pulled back string on an archer's bow is an example of Potential Energy.
