We can use formulas to model real-life situations. For example, the formula for calculating speed is speed = distance ÷ time. It is possible to calculate the speed, distance or time if you have ...

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 relationship between acceleration, velocity change and the time taken for the change is given by this formula ... in 4 seconds. Calculate the acceleration. The change in velocity v ...
