Thank you so much. I am not from science background. Still, I am able to understand your explanation. You are a great teacher. Thanks for making such a helpful video!
just to point out those are not the only fundamental dimensions, they are the fundamental dimensions used in mechanics but there is also luminosity, current, substance amount and temperature :)
Its very easy M se mass or C speed of light in vacuum & speed =distance/time so distance is L and time is T then we get LT^-1but we are given that mc^2 so (distance/time)^2 so we get L^2T^-2. So the dimension of E=mc^2 ML^2T^-2
Velocity is the rate of displacement isn't it? As oppose to distance. Speed is the rate of distance. Velocity is a vector quantity and Speed is a scaler. In which case it would be [dLT^1]? But now that I think about it, delta length is still a length. Anyway some clarification would be great.
Think it was just because the purpose was to show they have the same dimensions. (i.e. 0.5 is a unitless dimension, and therefore wouldn't affect it in terms of dimensional analysis). I know this is very late lol but just incase someone can reply an correct me
How do I solve this problem: A swimming pool measures 20 ft, by 10 ft, by 4 ft. If water has a mass of one gram per milliliter how many tons of water are in the pool? Do I go from feet to grams to ounces to pounds to tons? Also, I can't figure out how to go from feet to grams because I don't think you can do that since there is no conversion factor... SOS I just started physics and I'm dying.
Sir I think you.You have explained dimensional analysis in 8 mins. It took my professor a good 3 hours to do the same. Note he never really answered he just jumped around it giving vague explanations.
I see, sounds easier than before. You are way (100 times) better than my physics teacher, Thank you. But I have a doubt, can you please clear it to me? Ke=1/2(mv)2 but why didn't 1/2 had any sort of effect in the dimension? I guess real numbers are usually ignored in dimensions... Please correct me if I'm wrong.
Anybody knows how to solve this . . . Kinetic Energy, KE has dimensions (kg)(m^2)/(s^2). It can be written in terms of the momentum P, and mass m KE=p^2/2m a) determine the proper units for momentum using dimensional analysis
You explained this so much better then my physics instructor! thank you so much!
Learned more through this video in 7 minutes than my professor in 2 hours. Thank you sir.

Thank you so much, you're a lifesaver! I understand the concept much better now.

Good video. Keep it up
thanks I am in class right now and I could not understand, but you made everything so easy to understand.
If anyone wants to do it another way, you can use Work = Force x Distance for the Energy part (Work is a form of energy)
Awesome video, really clarifies the concept.
Great video well explained
I really get rightfully thanks ur a magnificent and a great teacher🎉
"einstein was of corse right"...the best part!!!....nice vid...respect man!!!
wow! i love the video.
Thanks for that dude I appreciate you so much man
Thank you so much it was so informative...was not it??even after 11 years ❤

Thank you because of you I was able to write the test
Me watching this after eleven years!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 😂😂
you made me understand this thing better thanks
Really this helped thanks sir
Thank u sirrrrrr......!!!!!!
Thank u very muchhhhhh......!!!!!!!
thanks bro
it's really help full
Thanks sir love from india
DAMN!! I love you bro thanks

Oh thank you so much for this.
👍👍👍👍👏👏👏🤜🤛
This was very helpful. Thank you!
i greatly appreciate
Thank you very much. ....you help me a lot
Great vid mate !
It's really helpful
Helped a lot
O nthusitse fela thata 😌❤️ tanki
Wow thanks brother
Thank you so much, now I get it ♥️
what about charge, is it dimensional?
Is 1/2 in KE ignored in such cases and if so,why??
Think it was just because the purpose was to show they have the same dimensions. (i.e. 0.5 is a unitless dimension, and therefore wouldn't affect it in terms of dimensional analysis). I know this is very late lol but just incase someone can reply an correct me
constant are ignored :)
@@firdauspuzi1145 constants are not ignored if they have dimensions e.g ideal gas constant.
Thanks man, this really helped ! I appreciate it.
For KE, shouldn't it be = [ M x L^2 x T^-2 / 2 ] ?
tinisha bawa I
the constant has no dimension so the 1/2 isn't factored in at all
v.helpful thanks
Thanks bro you helped me
Thank you so much bro solved!!!!
dimensional analysis for frequency formula?????

Thank you sir.
You are big :D

No is constant also pie is constant can br changed
M[1]
S[10]
K[100]
Q[1000] Coulomb
D[10000] Temperature
L[100000] Mole
Thanks
nice
thankssssssssss

watch some worked examples here ua-cam.com/video/rsz4PRAOiTg/v-deo.html, they could help you figure out how to solve the number
you saved my life xD
1st year eh :D
lmao, uses dimensional analysis to prove Einstein right.. nah bro.. you used Einstein to prove dimensional analysis right
My brother
