Energy Transfer by Working

What is energy?

• moving from one place to another

• the power to do things

• the ability to do work/cause change

• doing jumping jacks

What is work?

• the ability to do work/cause change

• The movement of objects and substances from one place to another

• The transfer of energy to an object by a force that makes the object move in the direction of the force

• The energy that is stored in objects by a certain force
