How do you find the power used by gravity to force an object down toward the ground given weight, displacement, and time?

A block weighing 50 Newtons falls 45 meters before hitting the ground. If it takes 3 seconds for this block to fall, then how much power does gravity use up in bringing this ball down?

Summary

  1. N- Newtons
  2. d- distance
  3. m- meters
  4. t- time
  5. s- seconds
  6. Pg- power that gravity uses
  7. The weight of the block is by definition the force of gravity on the block!
  8. Fg with an arrow- force of gravity vector
  9. Watts- units of power

Notes

    1. t- time, s- seconds
    2. d- distance, m- meters
    3. Fg with an arrow- gravitational force vector on the block, N- Newtons
    1. Pg- power that gravity uses
    1. P- power
    2. W- work
