In this video, we explore five key areas of physics: **Classical Mechanics:** Newton’s second law (F = ma) explains the relationship between force, mass, and acceleration. The law of universal ...

Speaker one We’ve been using Sir Isaac Newton’s theories for hundreds of years and still use his equations today. Now, how can we test Newton’s second law using equipment found in our laboratory?

The questions in this quiz are suitable for GCSE physics students studying terminal velocity, Newton's first, second and third laws and braking. If you struggled with the quiz, don't panic - we've got ...

The equation F = ma is one of the most important in physics. Yet we have so far not explained how to get a quantitative operational definition of either mass or force. Somehow, from this one ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. This helps, sort of, but as more numbers get thrown around, it can get ...
