Question

slope of the velocity time graph gives !

Answer 1

let velocity (v) at y axis and time(t) at x axis.
then the slope of the curve is dv/dt
which gives the acceleration.
as dv/dt=a.

Answer 2

Consider the figure given below.





The fig. shows the velocity-time graph for a body in uniform acceleration.

Graph is a straight line inclined to the time-axis.

Body has velocities u and v at times t1 and t2respectively.

,



= Acceleration of the body

Hence, the slope of the velocity-time graph gives the acceleration of the body.
