3. gravitational force exerted on an object
5. a push or pull on an object
7. (2 words) combined forces that form a net force that is not zero
10. (2 words) rate of change of position in which the same distance is traveled each second
11. at rest or having no motion
14. (2 words) given direction from a starting point to describe an object’s position
20. amount of matter in an object
21. (5 words) acceleration is equal to the net force exerted on the object divided by the object’s mass
24. (2 words) combination of all the forces acting on an object
25. tendency of an object to resist a change in its motion
26. process of changing position
27. object’s distance and direction from a reference point
29. (2 words) forces that two objects apply to each other

1. (5 words) the motion of an object does not change if the net force on an object is zero
2. measure of how hard it is to stop a moving object
4. (2 words) a force in circular motion that acts perpendicular to the direction of motion toward the center of the circle
6. (5 words) total momentum of a group of objects remains the same unless outside forces act on the objects
8. (2 words) starting point you choose to describe the location, or position, of an object
9. measure of the change in velocity during a period of time
12. (2 words) a push or pull on an object by another object that is touching it
13. force that resists the motion of two surfaces that are touching
15. (5 words)for every action there is an equal and opposite reaction
16. difference between initial position and final position of an object
17. distance an object travels per unit of time
18. (2 words) a force one object can apply to another object without touching it
19. (2 words) combined forces form a net force of zero
22. (2 words) speed at a specific instant in time
23. speed and direction of a moving object
28. attractive force that exists between all objects that have mass
