Although these restrictions sound severe, the Bernoulli equation is very useful, partly because it is very simple to use and partly because it can give great insight into the balance between pressure, ...

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 ...

It is the amount that velocity changes per unit time. The change in velocity can be calculated using the equation: acceleration (\(\text{a}\)) is measured in metres per second squared (m/s 2 ...
