Oh I just realized you can break the forces down like this in any inclined plane (with the vertical component always being cos(theta)). Nobody seems to say that, and I don't even think you did. Helpful all the same, thanks
I certainly enjoy your videos. I have a question based on this video. If a block is at rest on the incline plane at an angle of 30 degrees, would the maximum frictional force that would allow the block to stay in place be calculated using 30 degrees, OR would we have to find the minimum angle of the incline plane needed for the block to slide before we can determine the maximum frictional force? That is, find that minimum angle and then substitute it in the formula for fs(max) = UsMgcos (minimum angle needed for block to slide)?
I loved your style of explaining facts. I have no exams...but I love to recover my lost data, LOL (I did this things too many years ago...). I was good with forces, but I did not understand how that Theta angle jumps...from 1 triangle to another. I didn't bother to check, ufff simple explanation! Thank you!
Come to England and teach my mechanics class please? :) It's taken me most of the year to understand this, I found this video and BOOM! I get it now!! :D thank you so so so so much, you're a saviour!
If there is no friction then after the push while the block is travelling up the incline the physics is the same where a=gsin(theta) but it will have the opposite sign as v so it will be slowing down. During the push, F, the acceleration is a = Fnet/m or a =(F-mgsin(theta))/m.
Omg ur the goat. I been wondering why the heck do we use MG SIN THEETA for the INCLINE. like no1 explains it, it was just a formula. But u demonstrated by trig why we use it.
Usually, but it's different with ramp problems. The angle of the ramp is equal to the angle between mg and the force opposing the normal force.So you're focusing on that angle. Looking at the following picture will help:
sin(theta)=opposite/hypotenuse and cos(theta)=adjacent/hyp. In this case, sin(theta)=(component of Fg in the x direction)/ (Fg) since the (Fg) is the hypentuse.
Dear Sir, Many thanks for your simple and precise explanation - especially clearly showing how X and Y Axis are considered for Sine and Cosine which is very easy to comprehend.
omg thank you I'm doing online schooling and they actually just gave me an example problem with no explanation just pt1 pt2 pt3 so I had to apply it without understanding it
No, the friction force is (coefficient of kinetic friction) x (normal force). In this case that turns into (coefficient of kinetic friction) x (mgcos(theta)).
Embarrased to admit I graduated college 8 months ago and didn't truly understand this until now. Better late than never. Thank you, sir.
college???? we are learning it here at grade 11th
Finally, someone who explain this so simply and effectively. Thank you!
Thanks so much, you managed to make clear what my physics teacher has failed to explain for the past 3 weeks
adanggoodmoviemaker thank you, u said exactly what I was gonna say
Iam in grade 12 and my Physics teacher isnt even trying to explain he is just throughing questions at us and we are supposed to answer
@@amrovine4029 we're learning this in gr11
@@davidismdumdu I'm learning this shit in 8th grade. I'm having a brain spasm trying to understand this
about to watch this... I hope it helps.. will the future me in 10 minutes know what the fuck he is doing? let's find out
nope... let's try part 2
hahhahahahhahhahahhahhahhahhah
Your comment made me so happy, thanks bro!! :DDDDDD
For a triangle, the height is sine of the angle and length is cosine of the angle.
For x and y, x = cosine(Ø) and y = sine(Ø).

My professor did not explain what he was doing at all when we were going over this. Thank you so much for making this video. You just saved my grade.

I agree with one of the previous comments, you make this subject more clear than my actual teacher. Great way to explain physics.
Thanks alot

I am revisiting calculus classes sat thru five of them and two or 3 physics classes. I have forgot a lot. enjoy your teaching.

I was looking for a way to show my class why that angle is theta. This is perfect. Thanks!
One of the best. Clear concise without unnescessary teh speak but accurate. Super vid.
Thank you for explaining how to get the inner theta! I was so confused before.
Thanks a lot for this video. Do you have videos with an incline where 1 block is pushed UP, and when 2 blocks together are pushed UP as well? 🙏🏻
If there is no friction then after the push while the block is travelling up the incline the physics is the same where a=gsin(theta) but it will have the opposite sign as v so it will be slowing down. During the push, F, the acceleration is a = Fnet/m or a =(F-mgsin(theta))/m.
Best physics tutor up to date, I wish I had found you a week ago and I would have sure A in my first term

this has been extremely helpful! it makes so much sense with the mathematical approach :)

thank you so much sir this has been the biggest problem for me in this course
thank you so much your videos helped me a lot in entrance examinations!!!!!!
Nice video just that you mixed up the cos and the sin on the x and y planes
wow thank you soo much I was so confused on how to get the coordinate axis but you made it real easy!! Thanks soo much!!
Thank you so much. This really helped me. My professor does not help.
This saved my grade. Thank you
im a college student and this video has cleared off some of my doubts! thank you so much!!!
Finally my physics lessons in school makes sense!!! Lol Thanks for the upload
Its good lecture because language used is well understood for all,this make physics easy understading
by far the most clear explanation well done!!!
OHHHHHHHHHH I FINALLY UNDERSTAND
i have a physics test tomorrow and my science teacher doesn't teach well. thank you so much
ps its been 11 years but thids video has such good quality for its time, wow
Saving me from failing at physics! Thanks from Czech republic!
You are amazing. Thank you for sharing your knowledge. You saved me for my exam.
wow, I couldn't have asked for a better explanation. Thank you!
You are so good at explaining, you beautiful man, bless
thank you so much i am studying physics and i did not really understood the material until i saw this video!!!
thank you sir !!!! you explained it in awesome way especially the angle ...
You made this so much easier to understand. Thank you!! You have a new subscriber :)
This is helpful but I would like to know how did you come up with the equation Acceleration=mgsintheta/m? Thank you!
Newton's Second law,
it is a rearrangement of F=ma
omg thank you I'm doing online schooling and they actually just gave me an example problem with no explanation just pt1 pt2 pt3 so I had to apply it without understanding it
If only my professor taught like this...
Thank you, this helped me a great deal.
Excellent explanation. Thank you.
You have taught me more physics in nine minutes and forty seconds than my physics teacher has all year! Thank you!
You have helped me so much Thankyou!
THANK YOU ! NOW I UNDERSTAND!!
Thanks for sharing this important video
very well explained ... thank you
whats the purpose of setting up the coordinate system?
You just made my life so much easier!!!!
wow! thank you, this is so clear!
awsum... keep posting such videos ... thank u ..
Very good lecture 🙏🙏🙏🙏
I love you, whoever you are.
Thanks for sharing this information
you sir are just amaaaaaaaaazing
Clear explanation..Thanks!!
Anyone here knows what’s the best thing to slide down for 20s on a 31.6 m ramp?
Great vid 👌👍
At the end of the video he's like "alright good luck." yeaaa im really gonna need it
Amazing Saved my day
thanks, helped a lot
is a is as in fa and would i subtract ff from fa? thank you for the video
You a star!!
Thanks, it help a lot !🙌🏻
thank you that was very useful!!
THANKS!!! actaully I understand about Normal, wow thanks!! i hope tomorrows test will be a 5 :D
Helped a lot!!!!!!! tnks
I am an Indian sir I am happy with your teachings
thanks, I completely forgot how to get a=gsin(theta). Now, I got it
U help me grap the FBD. u r wondeful
you made it really simple and easy, where my professor made it really hard
great sir !!
i think you made a mistake, on 6:46 isn't it suppose to be y=sin and x=cos? idk i was taught that way so i'm confused...
8 years ago and still helping
You saved my life!!
you are a genius man.
Thank you so much
thank you!!!!..this video is really useful... :D
I love how half the people who commented/watched this video are UC Irvine students. Goes to show how much our physics professors suck.
and it would be funny if you are that professor
nice teaching
Thank you so much!
How do you find thita?
you made it very easy!!!!!!!!!
your voice reminds me of ted from how i met your mother
can you explain how you get mgcos fata and mgsin fata?
thank you!!
Thanks. very helpful!!
Short and sweet
Thankyou mate😀
very good !
Is mgsin(theta) the friction force too?
No, the friction force is (coefficient of kinetic friction) x (normal force). In this case that turns into (coefficient of kinetic friction) x (mgcos(theta)).
thank you so much!!!!!!!!!!!!
Thank you ! :)
damn u r are gud at this post more
I am Indian but I like you video thank you sir
If you are in GA can you apply to my school. lol thank you
thanks!!!
Thanks man
