Across
- 1. has magnitude but no direction
- 8. energy stored in an extended or compressed material
- 11. the rate of change of an object's velocity
- 12. the product of the force and the distance moved by the force in the direction of travel
- 14. has both magnitude and direction
- 15. the net force acting on an object
- 16. using a drawing often to scale to find the resultant vector
- 17. force x perpendicualar distance from the pivot point to line of action of the force
- 18. the point where rge ebtire weight of an object appears to act
- 19. the ratio of useful output energy to the total input energy of a device
Down
- 2. the total distance travelled by an object divided by the time taken
- 3. energy of an object due to its motion
- 4. the product of one of teh forces of a couple and the perpendicular distance between them
- 5. and object in equilibrium is either at rest or travelling with a constant velocity because the net force on it is zero
- 6. the rate of change of the distance moved by an object
- 7. the force that will give a 1kg mass and acceleration of one metre per second
- 9. the energy stored by and object by virtue if its position in the Earth's gravitational field
- 10. the force on an object cause by the gravitational field acting on it's mass
- 13. the distance moved by an object in a particular direction, measured from a fixed start point
- 14. the rate of change of the displacement of an object
