CConley Chapter 2/4

3. The distance divided be the time interval during which the motion occurred
6. The forces acting on an object that combine to produce a net non zero force
8. {p=mv} Momentum=mass x velocity
11. The total amount of momentum in a system is conserved.The absence of outside influence the momentum is conserved
12. The maximum velocity reached by a falling object that occurs when the resistance of the medium is equal to the force due to gravity
14. The change in velocity divided by the time interval in which the change occurred.
16. The cause of an acceleration of change in the objects velocity. Force is expressed in newton

1. W=mg weight=mass x free fall acceleration
2. The force between two objects in contact that oppose the motion of either objects
4. For straight line motion acceleration=final velocity-inital velcity/time
5. The force attraction between two particles of matter due to their masses
7. A quantity defined as the product of and objects mass and velocity
9. A quantity describing both speed and direction
10. The force acting on an object that combine to produce a net force that is equal to zero
13. The motion of a body when only the force of gravity is acting on it
15. The tendency of an object to remain at rest or in motion with constant velocity
