Question

whar defines acceleration in v-t graph​

Answer 1

Answer:

The acceleration is the slope of the v-t graph

Explanation:

A v-t graph is a plot between the velocity of moving with respect to time.

where the velocity is plotted in the y-axis and time in the x-axis.

The acceleration of a moving body is defined as the rate of change of velocity with respect to time. That is,

the acceleration is,

$a=\frac{V_{1} -V_{2} }{t_{1} -t_{2} }$

In a v-t graph, the acceleration is the ratio of change velocity(the y components) to change in time (the x components ) as shown in the figure given below.

so acceleration $a= y/x$ , that is the slope of the v-t graph

we can conclude acceleration is the slope of the v-t graph

Answer 2

Answer:

The region under a speed increase diagram addresses the adjustment of speed. All in all, the region under the speed increase diagram for a specific time frame span is equivalent to the adjustment of speed during that time stretch.

Explanation:

 Speed increase is controlled by the incline of time-speed chart. In case the time speed chart is a straight line, speed increase stays consistent. In the event that the slant of the straight line is positive, positive speed increase happens. On the off chance that the incline of the straight line is negative, negative speed increase or impediment happens.
