Torque: The ability of a force to rotate a body
about some axis.

The torque is larger
if the force is applied
further from the axis
of rotation.

In a freight yard a train is being put together from freight cars. An empty
freight car, coasting at 10 m/s, strikes a loaded car that is stationary, and the cars
couple together. Each of the cars has a mass of 3
