Work and Power

Cards (8)

  • Work is done whenever a force makes something move
  • 1 joule of work = force of 1 Newton moves an object by 1 meter
  • The unit for work is the Joule (J).
  • The formula for work is: Work done (J) =Work\ done\ \left(J\right)\ = Force (N) x Distance (m)\ Force\ \left(N\right)\ x\ Dis\tan ce\ \left(m\right) or W =W\ = FD\ FD
  • Power is the rate of work
  • The unit for power is Watts (W)
  • 1 Watt = 1Joule/second
  • The formula for power is: Power (W) =Power\ \left(W\right)\ = Work Done (J)Time Taken (s)\ \frac{Work\ Done\ \left(J\right)}{Time\ Taken\ \left(s\right)}
