Expert Answer
1.) work done depends on the force applied and displacement produced (work = force x displacement)
2.) Power of a body depends on how fast work is done i.e. it depends on the quantity of work done in a particular time (power = work/time)
3.) K.E depends on the mass and velocity of the body (K.E = (1/2)x mass x velocity2 )and P.E. depends on the mass, acceleration due to gravity and height of the object above the surface of earth or any other planet (P.E. = mass x acceleration due to gravity x height)
