4. 3 m/s north is an example of a(n) velocity.

5. The relationship among speed, distance, and time is s = d/t.

6. A single point on a distance-time graph tells the instantaneous speed.

7. A merry-go-round horse moves at a constant speed but at a changing velocity.

8. Acceleration is rate of change of velocity.

9. If you ride your bike up a hill, then ride down the other side, your acceleration is first negative, then positive.

10. The equation used to find acceleration is a = vf – vi/t

12. Inertia varies depending on mass.

13. Newton's first law of motion is also called the law of inertia.

14. The upward force on an object falling through the air is air resistance.

15. The relationship among mass, force, and acceleration is explained by Newton’s second law of motion.

16. A feather will fall through the air more slowly than a brick because of air resistance.

20. When an object moves in a circular path, it accelerates toward the center of the circle as a result of centripetal force.

21. The path of a projectile is curved.

22. For any object, the greater the force that's applied to it, the greater its acceleration will be.

23. The size of the gravitational force between two objects depends on their masses and distance between them.
