Question

derivation of three equation of motion​

Answer 1

Answer:

In case of uniform acceleration, there are three equations of motion which are also known as the laws of constant acceleration. Hence, these equations are used to derive the components like displacement(s), velocity (initial and final), time(t) and acceleration(a). ... The three equations are, v = u + at

Explanation:

Answer 2

Answer:

1 . v=u+at

Explanation:

1. acceleration = delta v \ time

delta v =v-u

a= v-u \ t

v = u +at

2. average velocity = v + u \ 2

average velocity = s \ t

v+u \ 2 = s\t

( u+at ) +u \2 =s\t

2u+at\2 =s\t

s = ut +at ^2

3. We know , a = v-u \ t or we can say t= v-u \a

also we know , v + u \2 =s\t or we can say

v +u \2 * t = s

this becomes - v+u\2 * v-u\a = s

( v + u ) * (v - u ) =2 as

(v ^2)- (u ^2) = 2 as
