Introduction Have you ever played a video game with a controller that used motion controls? Do you ever wonder how sometimes a smartphone seems to "know" if you're moving? How do these electronic ...

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 ...

Motion engineers can spend hours optimizing tuning parameters in servo-based systems, and still not get the performance they want. Their time may also be wasted if, at some point in the project, they ...

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 ...

A negative gradient shows the rate of “slowing down” or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The gradient ...

Acceleration close accelerationThe rate of change in speed (or velocity) is measured in metres per second squared. Acceleration = change of velocity ÷ time taken. is the rate of change of velocity. It ...
