A force causes a mass to change acceleration. It can be described as a “push” or “pull’ on a body.

Newton’s Laws of Motion tell us how forces change the way a mass acts.


A force is a vector. Depending on the problem we are solving, we may want to solve it in 2D or 3D. Look at Representation of Force

Fundamental Forces

My engineering specialty is mostly focused with forces that requires physical contact between objects. These are non-fundamental forces. Non-Fundamental Forces
