Question

PLease explain WHY DOES WORK DEPENDS ON THE FRAME OF REFERENCE?

Answer 1

Why does work depend on the FRAME of reference?

Force is invariant, that is forces are independent on the choice of reference frame. however are dependent on choice of Displacements frames. Consequently work done by force on a body depends on choice of frame, and so does change in kinetic energy If you are on board moving train and throw a ball forward, displacement of your arm 1ft in the frame of moving car of the train is small, work is small and kinetic energy of the thrown ball is also small.
