State the principle of homogeneity of dimensions and check the below equation is dimensionally correct or not V=u+at |
|
Answer» es that the dimensions of each term on both the SIDES of EQUATION are same, then the physical quantity will be correct.Explanation:The principle of homogeneity is that the dimensions of each the terms of a dimensional equation on both sides are the same. any equation or FORMULAE involving dimensions (like mass, length, time, temperature, electricity) have the terms with same dimensions. V=u+atwhere u = initial velocity (m/s) v= final velocity (m/s) a = acceleration (m/) t= time takenL.h.s dimensions for v = []R.H.S dimension of u = [] dimension of at = []dimensions of v,u and at are same. so the equation v=u+at is dimensionally correct |
