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 ...

Although these restrictions sound severe, the Bernoulli equation is very useful, partly because it is very simple to use and ... Lift is defined as the force acting on an airfoil due to its motion, in ...

There are various methods to measure acceleration due to gravity. At Higher level all rely on one of the equations of motion. The measurements required will depend on the equation used.
