Question

For uniformly accelerated motion derive v-s relation

Answer 1

Here, u is the initial velocity of the object. v is the final velocity of the object. t is the time passed to gain the final velocity from initial velocity. a is the acceleration.  We know, acceleration is the rate of change of velocity of an object with respect to time . Here velocity change from u to v in time t. So We can write,  a= (v-u)÷t or, at = v-u or, v = u+at  If the object start moving from a stationary situation i.e with a initial velocity 0 (Zero) then u will be 0 (Zero) therefore  v=0+at or, v=at
