Question

State how the velocity-time graph can be used to find the acceleration of a body.

Answer 1

Velocity-time graph​ ​
In velocity-time graph, velocity is plotted along Y-axis and time is taken along X-axis.

Since acceleration is the change in velocity per time taken, the slope of velocity-time graph gives acceleration.

From the above graph,
$Slope=\frac{BC}{AC}=\frac{Changeinvelocity}{Timetaken}=acceleration$
Hence, the acceleration of a body is the slope of the velocity - time graph.
