Potential & Kinetic Energy

What have you done

today?

Energy

• Energy- the ability to do work• You have to have energy to do

everything you do!• The more energy you have, the

more you can do.• Moving objects have energy

(duh) and still objects have energy!

What does “potential”

mean?

Potential Energy

• Potential energy- the energy stored in an object (still objects)• Have you seen any objects

today that were storing energy?

Examples of Potential Energy

Kinetic Energy

• Kinetic energy- the energy of a moving object• Have you seen any

objects in motion today?

Examples of Kinetic Energy

Changing Energy• Sometimes the type of

energy in an object can swap back and forth.• Think of a roller coaster!

Examples of Changing Energy

Rubber BandPotential Energy

• A rubber band that is stretched has potential energy.

Kinetic Energy

• When the rubber band is let go and flies through the air, it has kinetic energy.

CandlePotential Energy

• An unlit candle sitting on a table has potential energy.

Kinetic Energy

• When the candle is lit and burning, it has kinetic energy.
