if p is momentum then dp/dt = f right?
I've heard that dp/dt can be written as f = m(dv/dt) + v(dm/dt)
Can someone tell me what this actually means, because it would seem that m would be dependent on v and v dependent on m, so I am not sure how this would work out.
Also, can someone point tell me some important equations for springs other than f= -kx and e = .5kx^2
