Question

Mention the physical quantity shown by the slope of a speed time graph

Answer 1

When we draw the speed time graph, 
Speed will be Y-axis and time will be X- axis

and we know that slope of the graph = Y co-ordinate/X co-ordinate
                                                           = speed/time
                                                           =(m/s)/s
                                                           =m/s²

This is the acceleration

Answer 2

Answer:

The slope of velocity time graph is acceleration.

Explanation:

Derivation :-

X- axis = Time(t)

Y- axis = Velocity(v)

Slope of the graph

=  Y- axis/X- axis

= speed/time

= (m/s)/s

= m/s²

Hence , m/s² means acceleration.
