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 ...

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 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 normal component of acceleration is known as the “centripetal” component. It is proportional to the square of the speed, and inversely proportional to the radius of curvature of the path. The ...
