The Velocity - Time graph of a body having. non- uniform acceleration. is a straight line.

The SI unit of retatdation: is - ms^-2

In a Velocity - Time graph the area enclosed by the Velocity - Time curve and the Time axis givés the displacement travelled' by the body.

If acceleration is zero, the velocity is also żero.
