  1. 2. In physics, this is any interaction that, when unopposed, will change the motion of an object or mass multiplied by acceleration of the object
  2. 3. the SI unit of pressure, equal to one newton per square meter (approximately 0.000145 pounds per square inch, or 9.9 × 10-6 atmospheres).
  3. 7. Force exerted by a machine to overcome some type resistance
  4. 8. an attractive force between any two objects that depends on the masses of objects
  5. 9. (symbol is N) it is the SI unit of force. one unit of this is how much force is required to make a mass of one kilogram accelerate at a rate of one metre per second squared
  6. 12. the force that opposes the sliding motion of two surfaces that are touching each other
  7. 14. IMA is the symbol of this and it can be determined by effort distance divided by resistance distance
  8. 16. force/area or the continuous physical force exerted on or against an object by something in contact with it.
  9. 17. the tendency of an object to resist any change
  10. 19. Force exerted on a machine
Down
  1. 1. gravitational force exerted on an object
  2. 4. AMA is the symbol of this and it can be determined by resistance force divided by effort force
  3. 5. he stated that "Magnitudes are in equilibrium at distances reciprocally proportional to their weights."
  4. 6. this can be built from a combination of levers, pulleys, inclined planes (and relatives wedges and screws), and hydraulic cylinders.
  5. 10. it is described by useful energy out/total energy x 100%
  6. 11. its abbreviation is PSI, a sort unit of pressure
  7. 13. My teacher calls himself
  8. 15. the speed of something in a given direction or distance/time
  9. 18. it is described by force X distance
  10. 20. work/time or In physics, it is the rate of doing work, the amount of energy transferred per unit time
