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 ...

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 ...

Find out more about Sir Isaac Newton’s laws of force and motion at the amusement park, Silverwood. A force is basically a push or a pull. Forces like gravity, inertia, and momentum affect everything.

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 ...

Scientists often make measurements. The physical quantities they measure fall into two categories: scalars and vectors. Scalar and vector quantities are treated differently in calculations. Motion - ...
