What is the Couple of a force ?

A couple is a pair of forces, equal in magnitude, oppositely directed, and displaced by perpendicular distance or moment. The simplest kind of couple consists of two equal and opposite forces whose lines of action do not coincide.

A pair of forces which are equal in magnitude, parallel and opposite in direction. Where d = perpendicular distance between the lines of action of the forces forming the couple is called force couple

the closer the planet is to the sun, the larger the gravity
