12. How can you tell if an object is moving?
$100 Question from Motion
How can you tell if an object is moving?

13. $100 Answer from Motion
Look for a change in position when comparing the object to a reference point.

14. What is the difference between distance and displacement?
$200 Question from Motion
What is the difference between distance and displacement?

15. Distance measures the total length traveled
$200 Answer from Motion
Distance measures the total length traveled

16. What is the difference between speed and velocity?
$300 Question from Motion
What is the difference between speed and velocity?

17. Speed: rate at which an object moves; how fast it goes; s = d/t
$300 Answer from Motion
Speed: rate at which an object moves; how fast it goes; s = d/t
Ex: 30 m/s
Velocity: speed and direction of an object
Ex: 30 m/s east towards bridge

18. $400 Question from Motion
A cyclist turns a corner maintaining a constant speed. Is she accelerating? Why or why not?

19. $400 Answer from Motion
Yes, she is accelerating because she is changing direction. Acceleration is defined as a change in velocity. Since velocity includes both speed and direction, speeds up, slowing down, or changing direction is acceleration.

20. Explain how orbital motion works.
$500 Question from Motion
Explain how orbital motion works.

21. $500 Answer from Motion
Orbital motion is a form of projectile motion. The space shuttle’s path curves around Earth due to a combination or two motions happening simultaneously:
Horizontal motion due to the force of the shuttle’s engines launching it forward and vertical motion due to the pull of gravity.

22. What is the strongest type of friction? When does it occur?
$100 Question from Force
What is the strongest type of friction? When does it occur?

23. $100 Answer from Force
Static friction is the strongest, and it occurs between two surfaces at rest.

24. $200 Question from Force
Identify the net force and resulting motion of an object experiencing balanced forces.

25. There would be no change in the motion
$200 Answer from Force
Net force is 0 Newtons
There would be no change in the motion

26. $300 Question from Force
When you sat your pencil on your desk, the desk applies a reaction force that is equal in strength and opposite in direction. This is an example of Newton’s ________ law of motion.

27. Newton’s Third Law of Motion
$300 Answer from Force
Newton’s Third Law of Motion

28. What is Newton’s Second Law of Motion?
$400 Question from Force
What is Newton’s Second Law of Motion?

29. $400 Answer from Force
The unbalanced force required to move an object is equivalent to the objects mass times its acceleration.
F=ma

30. Gravitational force depends on what two factors?
