or \(= {ms}^{-2}\). A negative gradient shows the rate of 'slowing down' or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient.

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 formula for Bernoulli's principle is as follows: Here, p is the pressure exerted by the fluid, v is the velocity of the fluid ... and doesn’t change over time. Speed and pressure: There ...
