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
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
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
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.)
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.
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.

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!
This video needs more exposure. Thank you.

I appreciate your response. I’m glad to know folks are finding the content useful in their studies. Best of luck!
Wow you are the first teacher to make me understand this topic❤
Glad you found this helpful!
Wish my physic tutor was you.
Well explained...thank you and may GOD bless your carrier.
Thank you, i was struggling understanding it at my university and you helped me.
Great explanation!
Glad it helped!
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.

Glad it was helpful!
Thanks to you, I've finally made my homework. Thank you.
Thank you so much I really needed this
I have exams on Friday and I didn't have a clue on dimensional analysis
Good Video Sir. Keep it up
Hi folks, to those who are finding this video useful, what other specific topics would be helpful to cover?

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
This is amazing man thank you so much
thankyou so much man
Glad it helped!
thank you king
If v=u+as show that this equation his dimensionaly incorrect 😊
L/T=L/T +L/T².L
LHS #RHS
Incorrect
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.

Literally have an exam in 20 minutes
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.
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.

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.

Even a baby can get it. Elite level of teaching. wish best for you
@@mehmetsahapdonmez7897 Thanks!
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.
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.
Why are you always adding a T²
Because it’s better than adding a T^3… just kidding 😆.
It’s because acceleration has units of distance per time-squared.
But what if you are given force
The units work the same; the units of force is Newtons, which breaks down to kg*m/s^2, so the same rules simply apply.
@@garrisonturner5670you are the best
This is my biggest problem in physic 😢
