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