Velocity-time graphs Acceleration Acceleration ... is the rate of change of velocity. It is the amount that velocity changes per unit time. The change in velocity can be calculated using the equation: ...

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.

In these equations, the "zero" subscripts represent values at the start of the time interval and the "one" subscripts are at the end of the interval. This means that v 1 is the velocity after this ...

Pressure/velocity variation Consider the steady, flow of a constant density fluid in a converging duct, without losses due to friction (figure 14). The flow therefore satisfies all the restrictions ...
