Across
  1. 5. Velocity change per unit time
  2. 8. Distance travelled by a wave front per unit time
  3. 15. Change in distance per unit time
  4. 16. The overall or net effect of all the forces on an object
  5. 18. Energy cannot be created or destroyed. It can only be changed from one form to another
  6. 24. The point through which a single force on the body does not cause the body to turn
  7. 25. An object remains at rest or continues with constant velocity unless acted upon by a resultant force
  8. 27. Force of gravity on a mass of 1 kilogram
Down
  1. 1. Oscillations of particles are perpendicular to the direction of wave travel about an equilibrium position
  2. 2. The change of energy of an object is equal to the net work done on the object
  3. 3. A moving object on which the only force acting is its weight
  4. 4. Causes all the measurements to be either slightly bigger or slightly smaller than the true value
  5. 6. A system that has no resultant force and no resultant moment acting on it
  6. 7. For an object that is in equilibrium the sum of the total clockwise moments about a point is equal to the sum of the total anticlockwise moments about the same point
  7. 9. Maxiumum velocity of an object achieved when there is no resultant force acting on a falling body
  8. 10. A pair of equal and opposite parallel forces acting on a body, but not along teh same line, causing the body to turn about a pivot
  9. 11. If body A exerts a force on body B then body B exerts an equal but opposite force on body A
  10. 12. Force multiplied by perpendicular distance from the point to the line of action of the force
  11. 13. Change in displacement per unit time
  12. 14. Force applied x displacement in the direction of the force
  13. 17. An object's acceleration is directly proportional to the resultant force acting on the object
  14. 19. A quantity which has direction as well as size
  15. 20. Distance in a straight line from a specific point
  16. 21. Useful output power over input power
  17. 22. The precision of an instrument is the smallest non-zero reading that can be measured
  18. 23. Work done per unit time or rate of doing work
  19. 26. One force x the perpendicular distance between the lines of action of the two forces
