Although these restrictions sound severe, the Bernoulli equation is very useful ... Therefore, to find the velocity V_e, we need to know the density of air, and the pressure difference (p_0 - p_e).

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.

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or ...

Bernoulli's equation is a simple but incredibly important equation in physics and engineering that can help us understand a ...
