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. \(\text{acceleration}=\frac{\text{change in velocity}}{\text{time taken}}=\ ...

Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The gradient of speed-time and velocity-time graphs represent acceleration.
