# What is the difference between torque and moments because both of them are calculated the same way?

## Answer

A moment is the product of a single force about a point. E.g. when you push down on the end of a wheel brace on a nut on a car wheel.

A couple is two forces acting together, and the magnitude is the torque.

In the wheel brace example, the force produces both a couple (whose magnitude is the torque) and a force at the nut (which pushes the nut).

In a sense, they are the same, but there are subtle differences.
