Forces & Motion Unit 1

2. quantity that has both magnitude and direction
8. region of space that has a physical quantity at every point
10. Newton's law that an object at rest will stay at rest and an object in motion will stay in motion unless a force acts on it.
13. starting point you choose to describe the location or position of an object
15. push or pull on an object
16. contact force that resists the sliding motion of 2 surfaces that are touching
17. speed and direction of a moving object
19. difference between the initial starting position and the final position
21. object's distance and direction from a reference point
22. measure of the distance an object travels in a given amount of time
23. Newton's law that when an object applies a force on another object the 2nd object applies a force of the same strength on the 1st object but force is in opposite direction
24. measure of the distance an object travels in a given amount of time

1. simple model to understand what will happen to an object due to a force
3. when colliding objects bounce off each other
4. process of changing position
5. gravitational force exerted on an object
6. combination of all the forces acting on an object
7. - forces two objects apply to each other
9. forces two object apply to each other
11. attractive force that exists between all objects that have mass
12. Newton's law of motion that states the acceleration of an object is equal to the net force exerted on the object divided by the objects mass
14. push or pull on one object by another object that is touching it
18. measure of the change in velocity during a period of time
20. force that one object applies to another object without touching it
