Energy Transformations and Transfers

What is the stored energy of an object or material due to its position.

• potential energy

• mechanical energy

• thermal energy

• chemical energy

This is the energy associated wityh the movement of electrons through a wire or circuit.

• electrical

• mechanical

• nuclear

• kinetic

The faster an object moves, the more of this type of energy it has.

• moving

• potential

• kinetic

• gravitational

This is the energy of an object due to the motion of its atoms and molecules.

• chemical energy

• sound energy

• radiant energy

• thermal energy

All energy can change from one of these to another.

• form

• transfer

• transformation

• potato-------

This is the energy produced when an atom splits apart (fission) or when two atoms join to form one atom (*fusion).

• electrical

• atomic

• thermal

• nuclear

A lamp is plugged into a wall socket. Once the lamp is turned on, both light and heat come from the lamp. The energy transformation is:

• electrical to radiant and potential chemical

• electrical to radiant and thermal

• electrical to radiant and nuclear

• electrical to radiant and mechanical

If you rub your hands together, you will feel the effects of FRICTION. What energy transformation took place?

• kinetic to thermal

• mechanical to thermal

• potential to thermal

• thermal to kinetic

This image/caption describes which scientific law/theory?

• The Law of Conservation of Energy

• The Theory of Conservation of Energy

• The Law of Conservation of Mass

• Newton's Fourth Law of Motion

Which statement summarizes the Law of Conservation of Energy?

• Energy is never created, but can be destroyed when heat is created in an exchange

• Energy is never created or destroyed; it is only transformed from one form of energy to another.

• Energy is never created or destroyed. It is only created when energy is created from matter.

• Energy is never destroyed or created except when there is a nuclear reaction.
