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.

One of the key aspects of studying turbulence is the analysis of velocity gradients, which are essential for understanding how energy is transferred and dissipated in turbulent flows. Recent ...
