2 METHODS (TRICKS) to WRITE DIMENSIONAL FORMULA in PHYSICS | DIMENSIONAL

DIMENSIONAL ANALYSIS PHYSICS TUTORIAL - Two methods of writing dimensional formula of any physical quantity with the very good example to understand simply. One is quick method while other is little lengthier.

1. Quick Method of Writing Dimensional Formula -- For this, we should know the unit of the physical quantity. We break the units into base form, into fundamental physical quantities form and then we just write the dimensional formula as we come to know, what makes that physical quantity. For e.g.- Speed has unit m/s -- which means length/time so, dimensional formula of speed will be [L,T-1].
2. Longer method of Writing Dimensional Formula -- for this we need to know the formula of the physical quantity. Then , we put the dimensional formula of each and every physical quantity involved in the formula, that solving results us the dimensional formula of the required physical quantity. For e.g. -- acceleration = speed/ time = dimensional formula of speed/ dimensional formula of time = [L,T-1]/[T] = [L, T-2]

Thank you so much, sir!!! My lecturer skips a lot of things, I wouldn’t know how to do these without your help.

[harrowedhuman]

it is good to see teachers wd good language...

[mohammedabdullahkhan]

excellent bro
I wish my teachers could learn how to explain instead how much they explain

[satvikchandrakar]

Thanks sir now I solve these types of questions very easily. Thanks a lot sir

[mr.muiz__]

By using unit method it is easy then formula method
Unit method is easy to understand

So helpful! Wish I saw this 5 years ago!

Why in the dimensional formula of work do you take kg as M0?. It should be as M1.

[veeeeeeee]

For WorkDone formula using units....you wrote [M^0] instead of [M^1]...anyways great way of explanation.

[pegasusgod]

It's brilliant but, Why are u saying time as temperature ?

[bangarudorachilakalapalli]

Thank you sir...
Very helpful
Anyone can easily understand the calculation of dimensional formulas through your video
Thanks a lot sir...
Really helpful

[yudhviryadav]

Akash Das sir ur teaching method very nice and u can make it more effective by explaining example one by one.
Thnx

[prettygirlythings]

understood it clearly thank you so much
keep on making such amazing videos

[ramessesthegreat]

The fake accent lasted only for about 2 minutes into the video🤣🤣

[littleeinstein]

MLT means Mass, Length and Time not temprature!!! But however thanks a lot dude...You deserves more likes.

[samsundarsingh]

At last u commite a mistake. But u explained very well. I lik urvvoice😘😘

[kusumsaini]

Hey but this method is good for easy equations like Velocity, acceleration, density etc.. but what about quantities like magnetic flux, inductance, viscosity??

[ramakrishnareddy]

Wow you are 100% better than our teachers....

[rakeshpathania]

hi i really like your way of teaching. but when you explained the dimentional formula of workdone from formula form, you write the power of mass is 0, which is 1, but we understand it with ease and accuracy....thanks a lot...

[nikeeparandekar]

Shouldn't the dimensional formula of work done be M^1 L^2 T^-2??
