If you did not push the physics book, the book remains still (static) and the net force on the book is zero . Electric current and activity in electric circuits occurs because of a net electric force ...

A force is a push or a pull that acts on an object due to the interaction with another object. Force is measured in newtons (N). Forces are divided into contact forces and non-contact forces.

In particular, the nature of force and motion (not the Force, but the physics force). A force is an interaction between objects that causes a change in velocity. Change is the key word here.

You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...

What is quantum physics? Put simply, it’s the physics that explains how everything works: the best description we have of the nature of the particles that make up matter and the forces with which they ...
