The violent collisions that are a hallmark of and problem for the NFL involve frequently misunderstood physics of momentum and force. And thinking about why those points are misunderstood makes a ...

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 ...

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.

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 ...
