Revise IGCSE Physics by listening to these podcasts ... JAMES: Yeah, and there are two different types of forces, aren't there? ELLIE: Yeah, so there's contact forces and non-contact forces.

Pressure is a measure of how concentrated a force is. The amount of pressure exerted on an object depends on the force applied and the surface area it is spread over. Force diagrams and resultant ...

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 interact.

Protons and neutrons are both composites of three quarks of two types, or “flavours ... only through the weak force, are now an integral part of the particle physics canon, and perhaps ...

And the reason could be evidence of a new, fifth force of nature ... using the Muon g-2 experiment at Fermilab noticed a certain type of subatomic particle, called a muon, was wobbling more ...
