Question

Derive first and second equation of motion graphically.​

Answer 1

Answer:

object is moving with a uniform acceleration “a” along a straight line. Draw a line parallel to x-axis DA from point, D from where object starts moving. ... Draw another line BA from point B parallel to Y-axis which meets at E at y-axis.

Answer 2

Answer:

1. v=u+at
2. S=ut+1/2at²

Explanation:

1. a=v-u/t

at=v-u

v=u+at proved

1. average velocity = total displacement/total time

average velocity=u+v/2

( u+v)/2=d/t (put value of v)

(u+u+at) /2*t=d

(2u+at) /2*t=d

( u+at/2)*t=d

ut+at²/²=d proved
