The Law of Conservation of EnergyEnergy cannot be created or destroyed.

Energy TransformationEnergy only changes from one form

to another.

Chemical Energy Electrical Energy Radiant (Light) Energy

Page 3: EnergyTransformations. The Law of Conservation of Energy Energy cannot be created or destroyed. Energy Transformation Energy only changes from one form.

The energy starts as one type (the energy it USES)

The energy ends as a different type (the energy it GIVES)

Electrical Energy Light Energy

(Radiant)

Rubbing your hands together USESmechanical energy (movement)

and GIVES thermal energy (heat) your hands start feeling warm

Page 5: EnergyTransformations. The Law of Conservation of Energy Energy cannot be created or destroyed. Energy Transformation Energy only changes from one form.

Eating food USES chemical energy

and GIVES mechanical energy--you now have energy to move!

Page 6: EnergyTransformations. The Law of Conservation of Energy Energy cannot be created or destroyed. Energy Transformation Energy only changes from one form.

A fan USES electrical energy

and GIVES mechanical energy--the blades are now moving!

Page 7: EnergyTransformations. The Law of Conservation of Energy Energy cannot be created or destroyed. Energy Transformation Energy only changes from one form.

Can you identify the transformation?

You will need to be able totell what energy is USED and what energy it GIVES

Page 8: EnergyTransformations. The Law of Conservation of Energy Energy cannot be created or destroyed. Energy Transformation Energy only changes from one form.

What energy does it USE?

It uses ELECTRICAL energy, because you have to plug it in.

Page 9: EnergyTransformations. The Law of Conservation of Energy Energy cannot be created or destroyed. Energy Transformation Energy only changes from one form.

What energy does it GIVE?

It gives off microwaves which areRADIANT energy and THERMAL energy to heat the food.

Page 10: EnergyTransformations. The Law of Conservation of Energy Energy cannot be created or destroyed. Energy Transformation Energy only changes from one form.

It uses light waves from the sun,which is Radiant.

What energy does it GIVE?

It gives KINETIC energybecause it moves fast downhill.

Page 20: EnergyTransformations. The Law of Conservation of Energy Energy cannot be created or destroyed. Energy Transformation Energy only changes from one form.

It uses POTENTIAL and NUCLEARenergy from the atoms that will be split.

What energy does an atomic bomb USE?

Page 21: EnergyTransformations. The Law of Conservation of Energy Energy cannot be created or destroyed. Energy Transformation Energy only changes from one form.

What energy does anatomic bomb GIVE?

It gives RADIANT energy as radiation, and THERMAL energy as heat.
