Starting with Newton’s first law of motion, we delve into how objects behave when they are at rest or in uniform motion. The second law unravels the relationship between mass, acceleration and ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

Tugging a small toy with your dog can be a lot of fun—but it’s also a great way to experiment with forces acting on an object. Forces are what scientists call the pushing and pulling on objects. In ...

Researchers have developed a concise approach to understanding the mechanics of human running. The research has immediate application for running performance, injury prevention, rehab and the ...

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 ...
