```										Dear Indrayani
v= u + at
s =( u + v ) t /2
s = ut + at2/2
v2 = u2 + 2as
The following are the variables used in these equations:
t is the length of the interval of time and measured in seconds.
u is the initial speed of the object or the speed at the beginning of the time interval, measured in ms-1.
v is the final speed of the object or the speed at the end of the time interval, measured in ms-1.
a is the acceleration of the object within the time interval t measured in ms-2.
s is the distance covered or the displacement of the object during the time interval t, measured in metres.

```										S=(u+v)t/2Derivation-We know that a=(v-u)/t and s=ut+(at^2)/2S=ut+((v-u)/t)t^2S=ut+(v-u)t/2Take t as commonS=t[2u+v-u]/2S=t(v+u)/2 Proved

```										we know that ( u + v )/2 is the average velocity in case of constant accelaration.we also know that average velocty into time is total displacement.now we have (u+v)/2*t=average velocity * twhich can also be written as (u+v)t/2=s
