Homework Statement
I've been watching calculus-based classical physics from MITcourseware just to learn physics. and I've been having this question that professor walter lewin did not address neither drphysicsa on youtube
the question is: knowing that W(from A to B)= the Integral of (F dx) and eventually u derive that you'll get change in kinetic energy ok i got that. But what is the different between that and W=Fx which is work=force times displacement?
there's also another equation that prof.WL addressed: dw=F(x.component)dx+F(y.component)dy+F(z.component)dz
and if you take the integral of that you get W by itself? so the rate of change of work is Force times displacement? isn't it just work itself?
Please help!
