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 ...

Physicists use the displacement formula to find an object's change in position. It sounds simple, but calculating displacement can quickly get complicated. Let's break it down using some solved ...

Sometimes you think you have a complete understanding of something and then BOOM—a simple problem throws everything out the window. Let's consider a very basic physics problem involving pushing a ...

Work close workEnergy transferred by a force. Work done = force × distance moved in the direction of the force. is done when energy is transferred from one store to another. Work is also done when a ...

It often feels like electronics will continue to get faster forever, but at some point the laws of physics will intervene to put a stop to that. Now scientists have calculated the ultimate speed limit ...
