Not a trick question, Imagine the object had to be moved up and down (attached to the cable if you like). and this movement was controlled by an electric motor. To hold the object in a stationary position the motor would still have to work to overcome the effects of gravity.

A fair question, However the object is to be suspended. Sam

Hi, I am trying to calculate the electrical power (watts) needed to hold a 500g object stationary against gravity. It’s been a while since my physics days and each time I do the calculations I come up with a different answer. Any help would be much appreciated. Thank you. Sam
