... It is clear that to make an object start rotating, a force is needed; Unlike in linear motion, the position and direction of the applied force matter as well. In the figure, the applied force will be more effective in opening the door than force assuming they both have the same magnitude. The angula ...

Newton`s Third Law
... First, we know that mass m is falling and dragging mass M off the table. The force of kinetic friction opposes the motion of mass M. However, we know that friction is negligible here because it is a smooth surface! We also know, since both masses are connected by a nonstretching rope, that the two m ...
