Mini-Quiz: Kinetic Energy Concerns Movement of Matter

1. What happens when you triple the velocity of a moving object?

   The kinetic energy is cut by 1/3Sorry, not correct. Try another button. The kinetic energy is increased by 3Good try, but not right. Select another answer. The kinetic energy is increased by 9That is correct. You are becoming an energetic Champion.

2. How does applying a force on an object result in kinetic energy?

   Force accelerates the object, causing it to move at some velocity and thus have kinetic energyCorrect. You are just plain smart. Force creates potential energy that can later be turned into kinetic energyOops! Wrong answer. Re-read the question and try again. Force is kinetic energySorry, not correct. Try another button.

3. What really is heat energy?

   The kinetic movement of molecules and atomsThat is correct. You are becoming an energetic Champion. A special form of energy, different from the othersGood try, but not right. Select another answer. Radiation, convection and conductionOops! Wrong answer. Re-read the question and try again.
