This really helped me out in my physics class at my college because I didn’t understand the lecture materials at all and was just stuck for what felt like an eternity
This 16 minutes was enough to help me understand what my teacher has been trying to explain for 4 hours. I couldn't understand my teacher's explaination for weeks but this video was super easy for me to learn from!! Thank you!! ❤❤
thank you for this video, i have been struggling with physics at my university and now is more clear to me hoy to do dimensional analysis, god bless you sir, have a wonderful year!
As someone who has been battling with dyslexia my entire life this video explains dimensional analysis very very well! I have looked at other videos and I have only grasped very little. Thank you. Looking forward to watching your other videos.
Thank you for doing this video, literally just come from my analytical studies tutorial and as per it's not failed to make me feel 1 inch tall, I'm on my foundation year, this is how it should be taught l.
my friend missed half of our unit for chem because he was out of the country and our disgrace of a teacher is making him take a test tomorrow on this .. he randomly found your video and is actually watching it as we speak 😭 hopefully these comments are true, wish him luck lmao
What would be the unit if the variable appears in mathematical power in exponential terms. For example, e^(alpha * t) is on side of the equation. Should the its dimensions always be nullified by the constant that comes with it?
When a variable appears as the argument of an exponential, trigonometric, logarithmic, or hyperbolic trig function, the overall argument needs to be dimensionless, so any constant that appears in the argument needs to cancel the dimensions of the variable out. So, in your example, e^(alpha*t), alpha would need units of inverse seconds (like frequency or angular frequency.)
i didn't get it in class , now am fine The lecturer wrote t=klmgn where m is index for l and n index for g , asked us to find the values of m and n help me pleasee
In most of the introductory examples, yes, because most of the equations in the next section are kinematic and thus use position/displacement, velocity, and acceleration.
The arguments of trig functions need to be unit-less. As a result, if you have something like y=A*sin(wt) where w is the angular frequency and t is time, then the units of w and t need to cancel out. Since t will be (in SU units) seconds, w needs to be (seconds)^-1 or radians per second.
Sure it is. It is also a useful conversion factor as well. It's not an equation in the algebraic sense with multiple variables, but it is an equation demonstrating an equivalency.

Bless you and your family! This was actually really informative and interesting. Sir, you wouldn't believe how much you have helped me!
Glad it helped!
Wish my physic tutor was you.
Well explained...thank you and may GOD bless your carrier.

Good Video Sir. Keep it up
Very nice teaching, thanks
Great lecture

I appreciate your response. I’m glad to know folks are finding the content useful in their studies. Best of luck!
Great explanation
This is a good lecture
Thank you for the video and keep on doing the good work
This was so helpful, on a topic I was really struggling with. You sir are the goat, may your pillow always be cold on both sides.
Hi folks, to those who are finding this video useful, what other specific topics would be helpful to cover?

Awesome 👍
Wow you are the first teacher to make me understand this topic❤
Glad you found this helpful!
A great lecture thank you :)
I’ve been watching dimensional analysis videos for hours and this is the first one that made sense. ❤
@@christopherporter2167 glad it helped!
Amazing video, you are a great teacher and this was very well paces. As a non-mathematics student, I got this immediately. Thank you for this upload 😬
This was very helpful for me. Thank you so much, sir
alhamdulillah. thank you prof
Very helpful 👍
Well explained
Amazing video
Thank you so much sir your explanation is better than my teacher.
Thanks to you, I've finally made my homework. Thank you.
Thank you sir very helpful
I just want to hug you man
Really helpful video!
Nice presentation
Thanks a lot!
Thank you, i was struggling understanding it at my university and you helped me.
Great explanation!
Glad it helped!
Really appreciate it
Thanks
Wow sir thank you for you have helped me know and understand
Thank you sir. God bless you.
Wooo thanks sir
Well explained 👍
Thanks!
Thank you for this information
Wow 😲😳. God bless you sir. I really needed this ❤
Cool video, thanks
Thank you so much I really needed this
I have exams on Friday and I didn't have a clue on dimensional analysis
Thank you for doing this video, literally just come from my analytical studies tutorial and as per it's not failed to make me feel 1 inch tall,
I'm on my foundation year, this is how it should be taught l.
Glad it was helpful!
This was such a great teaching
very helpful. Thank you!
Thank you very much! Much better explained then in my textbook!
Thank you for the video.
Thank you sir.
i really got guided in this video
Life saver, thank you 💫

Thank God I've understood it 😅
Amazing lecture!
This is definitely going to help me pass my JAMB
you simply this well done. I have seen others make it so complex
🙏
Helpful
This is really helping me 😊
Glad it did!
Thank you sir this really helped me in revising for my test
Glad it helped!
This is so helpful thank you❤
Thank so much sir ilu
Thank you ❤️💯 understood
Your just awesome
Omg this vid was so helpful, thx so much ♥♥

I love it ❤❤and Oliver twist ask for more you know 😊
Thank you so much for this!!!
Thank you sir you are the best
thank you sir
this simplified it for me, thank you!
Thank you so much for this video , However do you have any video with calculating indices of dimensionless
@@ORGANICLESJA what do you mean, indices of dimensionless?
@@garrisonturner5670 for Example ; t = ka^x p^y y^z , find the indices for x ,y and z
thank you Garrison !
thank you that answered my question!
Thank you very much!
Thank you.... patience 😊

This is amazing man thank you so much

His has helped me to understand
That's why we always use a [constant] to make an equation.
Perfect ty sm
THANK YOU
thank you king
Thanks
thanks to you
i didn't get it in class , now am fine
The lecturer wrote t=klmgn where m is index for l and n index for g , asked us to find the values of m and n help me pleasee
can you teg me in your next video conversion of units
Is there a specific part of unit conversions that is confusing? I might be able to help.
Thank youuuu❤
If v=u+as show that this equation his dimensionaly incorrect 😊
L/T=L/T +L/T².L
LHS #RHS
Incorrect
is it only length and time that are used
In most of the introductory examples, yes, because most of the equations in the next section are kinematic and thus use position/displacement, velocity, and acceleration.
Thank you so much sir, but I'm a bit confused on how one of the units was left out.
Can you give a time-stamp of where in the video you are referring?
@@garrisonturner5670 I think he means around 8:40
@@billyrose100 if that is the correct time, there was a square in the denominator, I erased it because it canceled with the T in the numerator.
thankyou so much man
Glad it helped!
How do i analyse SINCOSTAN?
The arguments of trig functions need to be unit-less. As a result, if you have something like y=A*sin(wt) where w is the angular frequency and t is time, then the units of w and t need to cancel out. Since t will be (in SU units) seconds, w needs to be (seconds)^-1 or radians per second.
That 1/2 is a number and numbers are dimensionless I think.?
@@RichardManda-lo9th time stamp? Yes, numerical/constant coefficients do not carry units.
hadir boss
Is x always equal to l?
Generally in physics, especially related to motion, yes, x, y, and z represent spatial coordinates and therefore carry dimensions of length.
thank u so much!
So, 2000 pounds = 1 ton is not an equation?
Sure it is. It is also a useful conversion factor as well. It's not an equation in the algebraic sense with multiple variables, but it is an equation demonstrating an equivalency.
I saw this late anyway , but it helps
Literally have an exam in 20 minutes
