Can we create artificial gravity, or is it still science fiction? In this video, we break the problem down using real physics ...

If the angular velocity of a link in a mechanism is zero, does this imply that the angular acceleration of that link is also zero? The short answer to that question is NO. If ω(t) represents the ...

The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, ...

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 ...

Luke Aikins went skydiving without a parachute. This is crazy---not because it's impossible, but because really bad things happen if you make a mistake. If you haven't seen the video, it shows Aikins ...

Newton's Second Law states that force equals mass times acceleration. This can be investigated using a set-up like this one. You can use this set-up to investigate how changing two separate factors, ...

The radio signature is exactly what we’d expect from a water-rich comet,” said one of the researchers, which captures the ...
