Work And Power Practice Problems Physical Science Answer Key. Power is the rate at which work is done and is calculated Since

Power is the rate at which work is done and is calculated Since the force is always perpendicular to the incremental distances traveled as the particle travels the loop, there is zero work done over each increment and zero total work as well. If a group of workers can apply a force of 1000 Newtons to move a crate 20 meters, what amount of work will they have accomplished?
