What is Energy?

elastic potential energy

A stretched rubber band has

joules (J)

Energy and work are measured in

position of an object or the shape

Potential energy results from the

energy

The ability to do work or cause change.

speed

The factor that has a greater effect on the kinetic energy of an object.

power

The rate at which energy is transferred.

gravitational potential energy (GPE)

This energy of an object is equal to its weight multiplied by its height.

kinetic energy

This energy of an object is equal to one half its mass multiplied by its speed squared.

transferred to that object

When you do work on an object, some of that energy is
