Question

Check the correctness of the equation v=u+at by dimensional analysis. Where v,u,a & t represent
final velocity, initial velocity, acceleration and time respectively

Answer 1

Answer:

To check the correctness of physical equation, v = u + at, Where 'u' is the initial velocity, 'v' is the final velocity, 'a' is the acceleration and 't' is the time in which the change occurs. From (1) and (2) we have [L.H.S.] = [R.H.S.] Hence by principle of homogeneity the given equation is dimensionally correct.
