6. Definition of power?

  • rate of work in times
  • rate of energy transfer (work done)
  • change in energy transfer

7. Principle of moments?

  • perpendicular distance is 0
  • resultant force = 0
  • forces are the same

8. Definition of Newtons third law

  • If a body A exerts a force on a body, then B exerts an equal on opposite force on A
  • F = Ma
  • The forces are equal but in opposite directions

9. Moment equation?

  • force x perpendicular distance from the axis
  • force x distance from the axis
  • force x perpendicular distance around a point

10. Definition of Work

  • force multiplied by distance
  • force multiplied by the distance moved in the direction of the force
  • force multiplied by the direction of the force
