Expert Answer
Acceleration a is defined as rate of change of velocity.
Let u be initial velocity of an object and it is accelerated . Let a be the acceleration and v be final velocity after time t
Change in velocity , dv = v - u
Rate of change of velocity = Change in velocity / time = dv/dt = ( v- u ) / t = a
Hence , ( v- u ) = at
v = u + at
