energy transformation

• when energy stays the same when traveling from one object to another

• The change from one form of energy to another form of energy.

• when light passes through an object freely

• movement of energy away and out of the source.

Does all of the electrical energy produced by this battery transform into light energy?

• Yes; because of the Law of Conservation of Energy.

• No; because the mass of the battery changes.

• Yes; because light bulbs are light producing devices.

• No; because some of it transforms into heat energy.
