it is very difficult to memorise all the dimensions of diffrent things,so i wanted to know is there any methord through which we can relate or find out the dimensions of diffrent things?

just remember the formulae...for ex. force=ma a=d/t2..we measure distance in length so its dimension will be L/T2 or LT-2 so the dimensional formula for force will b MLT-2 .similarly u can find the dimension of any quantity.

Debjyoti don't worry about memorizing dimensions. Dimensions of a quantity can be found by applying dimension analysis to a formulae where you know dimensions of other things. YOu may find it difficult in begining as you do not know much formulae but as you progress in physics taht becomes easy

To learn dimention. Understand Relation between whole dimentions.
because all dimention are related to each other.

First know the dimentions of basic physical quantities like force,velocity etc. Then for other physical quantities find its relationship with basic physical quantities and apply dimentional analysis, you will get the answer.

Learn the formulae of of different physical quantities.These formulae are always helpful. Practice to write the dimensional formula of the basic physical quantities like volume, area, density, speed, acceleration, force, work. Then u can write the dimensional formula of all most all physical quantities, if u know its formulae
