Can work be done on a system if there is no motion?
I would say no, no motion = no energy...
Is it possible for a system to have negative potential energy?
I would say yes, since the choice of the zero of potential energy is arbitrary.
A 500-kg elevator is pulled upward with a constant force of 550N for a distance of 50 m. What is the work done by the 550N force?
From what I understand, we multiply 550N by 50 m, and get about 3.00x 104 J.
Thanks for your help!
