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. A force ...

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 ...

Try these interactive flashcards based on GCSE physics past papers. By working your way through the flashcards created by experts, you can prepare for your physics exams and make your revision 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 ...

Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

Physicists are facing a paradoxical situation. On one hand, they are searching for a fifth fundamental force that could ...

In many people’s minds, the primary focus of physics is on the very large (black holes, the distant universe and the problems of cosmology) or the very small (the Higgs boson and the other subatomic ...

Two physicists in the US have come up with a way to use a “bubble” of ultracold atoms to measure extremely small forces. The scheme, which has yet to be tested experimentally, involves monitoring the ...
