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 ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...

Why do things fall? It’s about force and motion. Find out more in this Science Trek short. A force is basically a push or a pull. Forces like gravity, inertia, and momentum affect everything. On this ...

This series of short explainer films with Professor Brian Cox comprises six clips focused on forces, speed and motion. Each clip uses simple terms and concrete examples to explain deep concepts that ...

Find out how forces and motion make our world move in the Science Trek: The Web Show. The world is full of motion and motion happens because of force. On this episode of Science Trek: The Web Show, ...

Units of measurement are are used to represent physical quantities like length, weight and other values. Units can be imperial or metric and can be converted by conversion factors. The movement of ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...

I see this problem all the time. The idea that if you apply a constant force on an object, it should move at a constant speed. Really, this is what Aristotle would say, right? There are two course ...
