Question

drive the formula V =u+at by graphical method

Answer 1

hii
derivation of V= u+at .
this is velocity rime graph

Let us draw AD parallel to OC
from the graph we observe that

BC= BD+DC = BD+OA

substituting BC=v and OA= u,

we get v = BD+ u
or BD = v-u _________________(1)

from the velocity time graph, the acceleration of the time of the object is given by
$a = \frac{change \: in \: velocity \: }{time \: taken}$


= BD/AD= BD/OC

substituting OC=t we get,
$a = \frac{bd}{t}$


or, BD =at _______________(2)

using equation (1) and(2) we get,
v=u+at
