... (1) heat: Energy can also leave or enter the gas as heat. For example, collisions between a molecule in the gas and the atoms in the wall will in general be inelastic, i.e., energy will be exchanged (see Fig. 1.1). The walls and the gas will be said to be in thermal equilibrium when, if we average o ...

AP Physics – Applying Forces
... We’ve learned that forces change the velocity of an object. But what does it take to change the angular velocity of a thing? Well, forces are involved, but the force has to be applied in a special way. We call this special applied force a torque. There are many ways to apply a force to a system that ...
