Physics Joke

Alright my turn to tell a joke hahaha.

As lectured by Prof. Nicholas

1a) Define moment of a couple. [2]

Moment of a couple is defined as the product of one of the force and the perpendicular distance between them.

1b) Define product of a couple. [2]

Product of a couple is defined as the product of one of the moments and the negligible perpendicular distance between the couple.

Now that's physics for you! :p
