Question

v=u+at prove and tell fast​

Answer 1

Answer:By definition method we can prove that :

Explanation:Acceleration = (change in velocity)/time taken

=( final velocity - initial velocity )/time taken

=> a = (v-u)/t

Or at = v-u

Or v = u+ at

Answer 2

Answer:draw a line AD parallel to OC in a graph

BC=BD +DC=BD + OA

SUBSTITUTING BC=v and OA=u

We get v=BD+u

BD=v-u equation 1.

From the velocity time graph the acceleration is given by

a=change in velocity÷time taken

=BD÷AD=BD÷OC

SUBSTITUTING OC =t ,we get

a=BD÷t

or

BD =at. equation 2.

from equation 1and2 we get v=u+ at
