Section Summary
... The force that two surfaces exert on each other when they rub against each other is called friction. It acts in a direction opposite to the direction of the moving object. Friction will eventually cause an object to come to a stop. The strength of the friction force depends on two factors: how hard ...

... What we have got here is that nothing is moving in the system, and yet it has a linear momentum. Something has to move, so what is actually moving in this system? It turns out that there is a mechanical momentum associated with the current flow, locating this momentum is not easy, and it is actually ...
