1. The force exerted by ropes and chains is called

• normal
• tension
• gravity
• friction

2. Name the missing force

• tension
• air resistance
• normal force
• spring force

3. A man pushes a box across the floor at a constant velocity. There is a force from the man pushing on the box. This is the ...

• gravity
• applied force
• friction
• normal force

4. Whenever an object is moving, there is always this force opposing the motion:

• applied force
• inertia
• friction
• normal force

5. The force that keeps objects on top of surfaces instead of letting them sink into the surface is known as:

• gravity
• normal force
• friction
• air resistance

6. This object would be moving (pick all that are correct):

• left
• right
• up
• down

7. In a force diagram, or free-body diagram, the size/length of the arrow tells you this about the force:

• relative strength
• relative direction
• relative distance

8. The down-arrow in this diagram is most-likely:

• normal
• applied
• friction
• gravity

9. If this object were moving right, the left-arrow in this diagram is most-likely:

• gravity
• normal
• applied
• friction

10. Which of the following best describes the object in this diagram.

• a box sitting on the floor
• an apple falling
• an athlete running to the right
• skateboarding gliding to the left
