Answer 1

Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. They can be used to show acceleration and to work out displacement.

Velocity - time graph :-

• > the slope of velocity time graph gives the acceleration of moving body . slope of v - t graph for time (t² - t¹ )

$⟹\frac{y \: intercept}{x \: intercept} ⟹ \frac{s {}^{2} - s {}^{1} }{t {}^{2} - t {}^{1} }$

$⟹\frac{ob \: - oa}{t {}^{2} - t {}^{1} } ⟹ \frac{v - u}{t}$

$⟹ acceleration$
