Force & Motion

1. force A force that causes an object to move in a circle
2. The rate at which velocity changes with time
5. A push or pull exerted on an object
9. is a measure of how much force is acting on a certain area
10. change in position over time
11. the speed of an object in a specific direction
13. First Law An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
16. a force that resists the motion between two surfaces in contact
20. the location of an object
21. The distance an object travels per unit of time
22. A measure of how much matter is in an object
23. force The combination of all forces acting on an object

1. of momentum the total momentum of a system of objects does not change, as long as no outside forces are acting on that system
3. The tendency of an object to resist a change in motion
4. Second Law acerbation of a object increases with increased force and decreases with increased mass
6. the moment when two objects hit each other
7. The force that exert on each other because of there masses
8. A quantity that has both size and direction.
12. point a location to which you compare other locations
14. Third Law For every action there is an equal and opposite reaction
15. resistance the friction due to air
16. a substance that can flow easily
17. the elliptical path one body(such as the moon) follows around another body (such as earth) due to the influence of gravity
18. the force of gravity on an object
19. The product of an object's mass and velocity
