Across

4. To speed up.

5. All objects in the universe attract each other through gravitational force.

7. Mass x Acceleration.

9. A force that opposes motion between two surfaces that are in contact.

11. When the force applied to an object does not cause that object to move.

14. The rate at which velocity changes over time.

15. Mass x Gravity.

17. The curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth.

20. The tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside

force acts on the object.

21. The force that resists the initiation of sliding motion between two surfaces that are in contact and at rest.

22. A force exerted BY an object. For example, a soccer player kicking a soccer ball; the force exerted ON the foot BY a soccer ball.

24. A substance that is applied to surfaces to reduce the friction between them.

25. Mass x Velocity.

26. An action exerted on a body in order to change the body's state of rest or motion.

27. The combination of all of the forces acting on an object.

29. The distance traveled divided by the time interval during which the motion occurred.

Down

1. The speed of an object in a particular direction.

2. A stationary object that indicates motion.

3. When the force applied to an object causes that object to move.

4. The change in an object’s velocity divided by the time in which the change occurs.

6. When an object covers equal distances in equal amounts of time.

8. When gravity is the only force acting on an object.

10. Speed measured in an infinitely small time interval.

12. An object's change in position relative to a reference point.

13. kg x m/s2

16. The force that opposes the movement of two surfaces that are in contact and are sliding over each other.

18. The change in position of an object.

19. The force of air resistance becomes equal to the force of gravity.

23. A force exerted ON an object. For example, a soccer player kicking soccer ball, the force exerted BY a foot ON a soccer ball.

28. A straight line on a velocity-time graph.
