Is more work done on a large or a small mass?
F = d/dt (mv)
W = Fd
The Attempt at a Solution
Greater the mass, greater the velocity according to F = d/dt (mv)
If the problem is given that
a glider of mass is free to slide along a horizontal air track
one asks this given question, should one consider that, since motion only exists in the x-direction, so the mass is an independent clause? Does this sounds right?
I mean in momentum, when a small mass hits a larger mass, we see the smaller mass moves at a greater velocity, assuming it is elastics.
However, when I look at W = E (mechanical energy) and KE, if the system is conservated with no external force, we always cancel out m (mass).
But how come the answer is "no difference"?
