The of the line on a velocity vs. time graph represents acceleration.

The slope of the line

Explanation:

In a velocity vs time graph, we have:

- The velocity represented along the y-axis

- The time represented along the x-axis

The slope of the line is given by

where

is the increment of the y-variable (the velocity), which therefore corresponds to the change in velocity:

is the increment of the x-variable (the time), which therefore corresponds to the change in time:

So the slope can be rewritten as

But this corresponds exactly to the definition of acceleration: so, the slope of a line on a velocity vs time graph corresponds to the acceleration.

true, as the earth rotates the sun hits the surface of the planet; causing the day and night cycle.
