One slug is the mass that will accelerate by one foot per second squared when acted on by one pound-force. The gravitational foot-pound-second English unit of force is the pound-force lbf defined as the force exerted by gravity on a pound-mass in the standard gravitational field of 980665 ms 2.

So as in the picture below you pull the rope down to lift the weight up.
. If you want to lift something that weighs 100kg you have to pull down with a force equivalent to 100kg which is 1000N newtons. Every matter that has mass exerts a significant amount of gravitational pull on its neighboring objects. In simple words gravity is the force of nature that drags a body towards the center of the Earth or towards any other physical object.
Gravity majorly depends on the mass of the objects and the distance between them. It is one of the strongest forces in nature. Tidal locking between a pair of co-orbiting astronomical bodies occurs when one of the objects reaches a state where there is no longer any net change in its rotation rate over the course of a complete orbit.
The pound-force provides an alternative unit of mass. If you want to raise the weight 1m into the air you have to pull the loose end of the rope a total distance of 1m at the other end. This is also called gravitational locking captured rotation and spinorbit lockingIn the case where a tidally locked body possesses synchronous rotation the object.
