2  1. Energy is the ability to cause change. Joules are used to measure energy.

3  2. The amount of energy an object has because it is in motion. The energy of motion.  Object +mass + speed

4  3. Mass and speed. More mass means more kinetic energy. More speed means more kinetic energy.

5  4. Potential energy is stored energy.

6  5. Gravitational: a tossed ball  Object +mass + height  Elastic: a stretched rubberband  Chemical: food, oil, coal

7  6. Heat energy.  It moves due to changes in temperature.  It always moves from hot or warm to cold.

8  7. Radiant energy.  Carried by waves. Spreads out in all directions.

9  8. The movement of energy from one place to another.

10  10. Energy transfer that happens when push or pull force moves an object.  Work = force + movement

11  9. By colliding or hitting another object.

12  11. Disturbances that move energy without moving matter.

13  12. Transfer of sound through vibration of an object. They must pass through matter such as air or water.

14  Horizontally across the surface of the water

15  They move through empty space, matter, & water. They spread out in all directions

16  light  infrared  microwave  xray  Radio  Gamma rays  Ultra Violet

17  Released through chemical reactions by breaking bonds or making bonds.
