What Is a Restoring Force in Physics?

TL;DR

A restoring force is any force that brings an object or system back to its position of equilibrium. For springs, this force is calculated using the equation F = KX, where K is the spring constant and X is the displacement. In simple pendulums, the restoring force is given by F = mg*sin(θ), where m is mass, g is gravity, and θ is the angular displacement.

let's talk about the restoring Force what is a restoring force a restoring force is basically any force that brings the object or the system back to a position of equilibrium so let's take for example the spring let me draw this better so let's say we have a spring that has been stretched Beyond its natural length let's say it's natural length is r...
