IB Physics Power

A tutorial sheet of questions on power is given below.

  1. Is power the gradient of the work-time graph?
  2. Is work done equal to the area under the power-time graph?
  3. Is work done equal to the average power multiplied by the time taken?
  4. A particle moves in SHM of period 12.0 s and amplitude 8.0 cm. Find the average power of the resultant force acting on the mass as it moves from x = +4.0 cm to the equilibrium position.
