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 ...

Although these restrictions sound severe, the Bernoulli equation is very useful ... Lift is defined as the force acting on an airfoil due to its motion, in a direction normal to the direction of ...
