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 ...

A school bus is travelling at 4 m/s. Its velocity then increases to 12 m/s. Calculate the average velocity of the bus over the journey. Final velocity = 12 m/s. Initial velocity = 4 m/s.
