5. Which of the following is a scalar? A. Velocity B. Acceleration C. 42 m/s to the right D. Speed E. D. Speed only give magnitude not direction

6. What does the following graph represent? Decreasing speed or deceleration

7. Which Newtonian term is used to describe the following situation? Inertia: Newton’s First Law of Motion

8. A speedometer gives the driver what information? A. Average speed B. Instantaneous speed C. Average velocity D. Overall acceleration Instantaneous Speed

9. What is the displacement in the following illustration? Zero Displacement: The runner finished where they started. 1 lap = 400 meters

13. What force is represented by the green arrow? Normal Force

14. Force is labeled in what unit of measure? Newton's (N)

15. The brown box in the second diagram is providing what type of force on the tennis ball? Centripetal Force

16. What (2) forces must be balanced to keep a satellite in orbit? Inertia Gravity

17. Determine the cars average speed. Speed = distance / time 5 miles /.2 hrs = 25 mph

18. What type of friction would the following object most likely experience? Rolling Friction

19. Why is the velocity of the (2) astronauts less than the velocity of the (1)? Increase in mass. Momentum = Mass x Velocity

20. For an object to accelerate, it must experience… A. Balanced forces B. Unbalanced forces C. Gravity D. Terminal Velocity Unbalanced Forces
