Systems of Masses (slide 8 to 11)
... 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 ...

Causes of circular motion
... a rigid object is located along the line for which it will balance. As shown below, when gravity is the only force acting on a rotating object, it will rotate around its center of mass (technically that point would be the object’s center of gravity, but for this book you can treat center of mass and ...
