The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time. \(\text{Gradient} = \frac{{change\,in\,velocity ...

Let's think now about the concept of motion and in particular ... to find either the distance travelled or the time taken. The speed equation is: \(speed = \frac {distance}{time} ...

Shown below is an animation of the motion of A and B as seen by a stationary observer. The paths of A and B are straight, as expected, with the speed of B increasing in time. View of B as seen by an ...
