If work is Force x Displacement, it would result to N x m, which is Joules. But then, kinetic energy is 0.5mv^2, which is kg x m^2/s^2. Can anybody tell me a way to prove that they have the same units?
Edit: I just found a way, but I am not sure if it is valid.
Weight is a force, and it is computed by: mass x acceleration, which is kg x m/s^2 (or Newtons) So, if KE is kg x m^2/s^2, then it becomes N x m
