2. What does Conservation of Energy mean?
Energy can flow from one object to another.
Energy cannot be created or destroyed.
It is converted from one form to another.
Energy in an isolated system is conserved.
This is also known as the first law of thermodynamics

3. What is Heat Transfer?
When thermal energy flows from a material at a higher temperature to a material at a lower temperature.

4. What are the three mechanisms of heat transfer?
Conduction
Convection
Radiation

5. What is Conduction?
Transfer of heat by the direct contact of particles of matter
Requires matter to transfer heat
Ex:
Taking a hot bath
Heat a piece of metal
holding your hands around a
cup of hot cocoa.

6. What is Convection?
Transfer of heat by the actual motion of a fluid (liquid or gas) in the form of currents.
Warmer fluids are less dense and rise. Cooler fluids are more dense and sink.
Requires matter to transfer heat
Ex: Hot water and ocean breezes

7. What is Radiation? Direct transfer of energy by electromagnetic waves.
Does not require matter to transfer heat
Ex:
Warmth from the Sun in the form of visible light
Infrared radiation (like your microwave)
A small amount of ultraviolet radiation

9. What is Potential Energy?
Energy of Position
Stored energy and the energy of position gravitational energy.
Something has potential to move!

10. What is Kinetic Energy? Energy of Motion
A form of energy associated with the motion of a body of matter.

11. What is Mechanical Energy?
The sum of the kinetic energy and the potential energy of a body of matter.

12. What is Chemical Energy?
Energy stored in chemicals and energy released or absorbed in chemical reactions are called chemical energy.

13. What is Friction?
The force exerted by a body of matter when it slides past another body of matter.
A force in the opposite direction of motion. E.g.. Rubbing hands together.
