Force & Motion Review

5. a pull or push that is applied to an object
8. an item against which the motion of an object can be measured
9. describes where an object is.
10. push or pull on an object that is not subject to an equal and opposite push or pull
13. limited period or interval, between two successive (one after another) events.
14. a force that opposes the motion of a body across a surface or through a gas or liquid
15. a force that can attract (pull closer) or repel (push away) objects that have a magnetic material like iron inside them (magnetic objects).
17. a change in the position of an object compared to another object (related term: move, movement)
18. distance traveled per unit of time
19. Law of Acceleration
20. a change in the velocity (speed, direction, or both) of a body

1. Law of Inertia
2. the amount of space between one point and another
3. when two equal forces are applied to an object in opposite directions, the object does not move
4. A location (object or places position) to which you compare other locations (or positions)
6. an object's resistance to a change in motion a change in the position of an object compared to another object (related term: move, movement)
7. a force that exists between any two objects that have mass
11. the resulting force determined by combining all of the forces acting on an object
12. the speed and direction of moving objects
16. Law of Action/Reaction
