Everyone needs some “go to” demos. Personally, I like this one. It’s not too difficult to build and it’s easy to use. Take a large block of wood (it needs to have a good mass). I used a left over ...

The simplest questions are often the best. Robert P Crease tries to answer one from a physics student in Kenya Seeking perfection Tennis balls are a low-cost way to explore simple physics concepts, ...

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 ...

We tend not to dwell on the fact that we exist in three dimensions. Forwards-back, left-right, up-down; these are the axes on which we navigate the world. When we try to imagine something else, it ...

Materials Needed: One large and one small ball and a room with a high ceiling. This experiment is very simple and it doesn’t require any dangerous and special materials. Take the two, one large and ...

In this video, I walk you through a super fun and simple balloon rocket experiment that you can set up in any classroom or at ...

Physics has a bit of a problem. Stuff that you don’t really think about, like single items moving on frictionless surfaces or two bodies traveling in the void of space, are really easy to explain.

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

Scientific history is littered with sophisticated theories that couldn't account for observations. Famously, the sensible and proven ideas of classical physics crashed up against the mysterious ...
