5. Which of these forces is a CONTACT FORCE that requires one force to push or pull the other?

• Frictional force that slows an object down.

• Magnetic Forces that push two objects apart.

• Gravity

7. When a book sits on a desk, which of the following best describes the forces currently acting on the book?

• The book doesn't move because no forces are acting on it.

• The book doesn't move because ONLY gravity is acting on it.

• The book doesn't move because although there are several forces acting on it, they all balance each other.

• The book doesn't move because ONLY static friction is acting on it.

8. If two different arrows represent 2 different forces, what does the larger arrow represent?
