Forces

2. forces that push or pull objects when the object contact each other.
4. the force of an object is proportional to its mass times its acceleration
5. the tendency of a body to maintain is state of rest or uniform motion unless acted upon by an outside force
6. measure of the force of gravity on an object
8. : A force exerted by one object on another in a direction perpendicular to the surface of contact
10. : A measure of the amount of matter in an object
11. A push or a pull exerted on an object that changes its state of motion.
12. create acceleration, cause a change in motion
14. force that pulls on a material (ex. rope, string)
16. pairs the action and reaction forces that act on an object and by an object; opposition in direction
17. : The combination of all forces acting on an object

1. : A force that opposes motion between two surfaces that are in contact
3. : A downward force that accelerates objects towards earth at a rate of 9.8 m/s2
7. Force acting over a distance
9. do NOT create acceleration - equal in strength and opposite in direction
13. : A unit of measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second per second.
15. A quantity that has magnitude and direction
