Question

what do you mean by the term work done. derive an expression for the work done. when displacement is 0 Angle with the force applied ​

Answer 1

Hey mate...

In the past, we derived that W = F d; such that the work done on an object is the force acting on the object multiplied by the displacement. ... This expression contains an assumed cosine term, which we do not consider for forces parallel to the direction of motion.
