1. Which of the following best describes the Law of Conservation of Energy?
Energy can be created but not destroyed.
Energy can be destroyed but not created.
Energy cannot be created or destroyed, only transformed.
The total amount of energy in the universe is constantly decreasing.
2. An object is moving at a constant velocity. What can be said about the net force acting on the object?
The net force is in the direction of motion.
The net force is opposite to the direction of motion.
The net force is zero.
The net force is constantly changing.
3. Newton's First Law of Motion is also known as the Law of .
4. The rate at which work is done or energy is transferred is called .
