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