Across
- 4. The force between two objects in contact that oppose the motion of either objects
- 5. The force acting on an object that combine to produce a net force that is equal to zero
- 7. The distance divided be the time interval during which the motion occurred
- 8. The motion of a body when only the force of gravity is acting on it
- 10. The total amount of momentum in a system is conserved.The absence of outside influence the momentum is conserved
- 13. 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 tendency of an object to remain at rest or in motion with constant velocity
Down
- 1. A quantity describing both speed and direction
- 2. W=mg weight=mass x free fall acceleration
- 3. The forces acting on an object that combine to produce a net non zero force
- 4. The cause of an acceleration of change in the objects velocity. Force is expressed in newton
- 6. The change in velocity divided by the time interval in which the change occurred.
- 9. {p=mv} Momentum=mass x velocity
- 11. A quantity defined as the product of and objects mass and velocity
- 12. The force attraction between two particles of matter due to their masses
