Potential & Kinetic Energy & Simple Machines

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. For example, a stretched rubber band has potential energy.

Front

What happens to Kinetic Energy when an object's speed increases?

Back

As an object's speed increases, its kinetic energy also increases.

Front

What is an example of a Simple Machine?

Back

An axe is an example of a wedge, which is a type of simple machine.

Front

What is Speed?

Back

Speed is the measure of how fast an object is moving. It can increase, decrease, or stay the same.

Front

How does height affect Potential Energy?

Back

The higher an object is positioned, the more potential energy it has due to gravity.

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 Potential Energy and Kinetic Energy?

Back

Potential Energy can be converted into Kinetic Energy when an object is in motion, such as a roller coaster going down a hill.

Front

What type of energy does a moving car have?

Back

A moving car has Kinetic Energy.

Front

What type of energy does a compressed spring have?

Back

A compressed spring has Potential Energy.
