What

is Energy?

Energy can be in motion or at rest​.

​

​Kinetic energy is what an object has when it is in motion.

​

Potential energy is what an object has when it ​is at rest or not moving. It is stored energy waiting to be used. It is also an object that is in position to move.

​

The rock has potential energy because it is not moving. It is pulled back in postition waiting to move.

Potential Energy

​

The soccer ball has kinetic energy because it is in motion.

​​Kinetic Energy

• ​Chemical (potential)

• Heat (kinetic)

• Light ((kinetic)

• Sound (kinetic)

• Electrical​ (kinetic)

​Some text here about the topic of discussion.

Potential and Kinetic Energy Has Different Forms.

​

Energy cannot be created or destroyed, it can only change form.

​For example: The boy holding the ball is an example of potential energy. When he drops the ball, it changes to kinetic energy.

-Transfer of energy-

The process of changing energy from one form to another.
