  1. 1. The kinetic energy of an object increases if which happens? DON’T FORGET TO SKIP A PAGE IN YOUR CRCT NOTEBOOK! • Its mass decreases. • Its speed increases. • Its height above the ground increases. • Its temperature increases.

  2. 2. When chemical energy is converted into thermal energy, which is true? • The total amount of energy changes. • Only the amount of chemical energy changes. • Only the amount of thermal energy changes. • The total amount of thermal energy plus chemical energy does not change.

  3. 3. An internal combustion engine converts thermal energy into which form of energy? • Chemical • Mechanical • Radiant • electrical

  4. 4. An example of chemical energy transformed into light energy is • A candle burning. • A light bulb shining. • A traffic light turning red. • A television screen lighting up.

  5. 5. Which form of energy does light have? • Electrical • Nuclear • Kinetic • Radiant

  6. 6. Muscles perform what type of energy transformation? • Kinetic to potential • Kinetic to electrical • Thermal to radiant • Chemical to mechanical

  7. 7. Earth receives energy from the Sun by • Convection • Conduction • Radiation • Temperature

  8. 8. As a ball rolls down a hill, it has less potential energy than it did at the top of the hill. Some of the ball’s potential energy • disappears • decreases • creates even more energy. • changes to kinetic energy.

  9. 9. Which of the following changes chemical energy into radiant energy? • Blender • Flashlight • Ceiling fan • Human body

  10. 10. What kind of energy is the archer giving the string of the bow? • Potential thermal • Radiant • elastic • kinetic
