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 questions in this quiz are suitable for GCSE physics students studying motion in a straight line, velocity and acceleration, distance-time graphs, velocity-time graphs and velocity, acceleration ...

Velocity is always TANGENT to the path. Acceleration, in general, has BOTH tangential and normal components. The normal component of acceleration always points INWARD to the path. The tangential ...

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?

A ride on a rollercoaster is a perfect example of physics in action. But there is much more at play than simply gravity and speed when it comes to the thrill of rollercoasters, as Michael Allen ...
