Energy Energy is the ability to do work The unit of energy is joules (J) When you do work on an object, you transfer energy to that object. Whenever work is done, energy is transformed or transferred to another system. Because energy is a measure of the ability to do work, energy and work are expressed in the same units. What: Why:

Energy is the ability to do work

The unit of energy is joules (J)

When you do work on an object, you transfer energy to that object.

Whenever work is done, energy is transformed or transferred to another system.

Because energy is a measure of the ability to do work, energy and work are expressed in the same units.

Potential Energy Potential energy is energy due to position, shape or condition Potential energy is stored energy

Potential energy is energy due to position, shape or condition

Potential energy is stored energy

Gravitational Potential Energy Results from the force of gravity Formula PE grav = mass x free fall acceleration x height PE grav = mgh Units: m = kg g = 9.8 m/s 2 h = meters Think: It’s going to have the potential to fall because of gravity Weight = mg

Results from the force of gravity

Formula

PE grav = mass x free fall acceleration x height

PE grav = mgh

Units:

m = kg

g = 9.8 m/s 2

h = meters

Think: It’s going to have the potential to fall because of gravity

Gravitational Potential Energy

Elastic Potential Energy Elastic potential energy is the energy stored when something is stretched or compressed Think: Rubber band that is stretched will pop back into place
