Mini-Quiz: Kinetic Energy Concerns Movement of Matter

by Ron Kurtus (10 October 2007)

Take this Mini-Quiz to check your understanding of the lesson material.



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

The kinetic energy is cut by 1/3

The kinetic energy is increased by 3

The kinetic energy is increased by 9

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 energy

Force creates potential energy that can later be turned into kinetic energy

Force is kinetic energy

3. What really is heat energy?

The kinetic movement of molecules and atoms

A special form of energy, different from the others

Radiation, convection and conduction

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
