- 3. A device used to measure fluid density
- 5. The combined force of many objects hitting an area
- 7. The resistance of a fluid to an obejct moving through it
- 11. It is the top speed
- 12. Enery stores that refer to the shape, position or state of an object. This could do work.
- 13. The ability to do work
- 16. The energy store that is equivalent to the temeprature of particles
- 18. The Young Modulus is like the materials spring constant but has considered its...
- 21. Causes rotational without translation
- 22. Lines of fluid flow are chaotic, at non-constant speeds and mix
- 25. Tensile or compressive
- 26. Distance travelled in a straight line from a reference point
- 29. The ratio of useful energy or power to total energy or power
- 32. The path often encountered when considering projectile motion
- 33. We often assume that this does not act in mechanics questions
- 34. A positive change in length
- 35. Can be described by magnitude only
- 36. Units of stress
- 38. The change in shape of an object
- 39. He noticed the link between buoyancy and weight of dispalced liquid (they are the same)
- 40. Hang this with a small weight to find the centre of mass of a laminar object
- 42. When the buoyancy is greater than the weight
- 43. The area under a force-displacemnt graph
- 44. When a quantity such as motion or field strength is constant
- 45. How easy or hard it is to stop something
- 47. This is the speed given on a speedometer. It is not the average

Down
- 1. A neasure of the compactness of a substance
- 2. The gradient of a velocity-time graph
- 4. It behaves like plastic when stretched
- 6. A force and change in length that have the same name
- 8. He noticed the relationship between force and extension
- 9. A force caused by the difference in pressure at its top and bottom surfaces
- 10. He came up with the laws of motion (and gravitation)
- 14. Units of strain
- 15. When an object hits another and exerts a force
- 17. The scalar quantity in SUVAT that applies to both the horizontal and vertical motion
- 19. The material will return to its original shape once the load force is removed
- 20. It is used to caluclate the viscous drag
- 23. Abbreviated to three letters. Point where the wire loses its strength, extends and becomes narrow at its weakest point due to the decrease cross sectional area
- 24. The spring constant represents this property
- 25. The near-parallel lines of fluid flow around an aerodynamic object
- 27. Horizontal acceleration for projectiles

- 37. A relationship where there is a constant linear relationship between each variable.
- 41. Lines of fluid flow are ordered, a constant speed and do not cross
- 46. A single resultant can be split into these
