Thanks for the video! Really helping me with my physics homework! I had a question where I was trying to figure out the maximum angle a driveway could be above the x-axis before it started to roll down given a coefficient of static friction = 0.94. And I figured it out! I'm so happy rn, AP Physics is actually destroying me.
@@FlippingPhysics I am retiring from the high school this year. So, it's good to know there are good young teachers around to teach physics. I made a donation in support. PS My real name is not Richard Feynman, of course LOL. It's a good alias. Most people have no idea who he is.
Very nice and enjoying way of learning... Bro u make me visualise the force in real world, those force arrows gives clear insight whats happening around. 😊
Bro i just wanna say.. I got one my type of physics understanding guy , its you 😎.. I love discussing quantum Mechanics and wants to go in every detail to unify macro level physics to micro.
Hi. Your videos are excellent! Do you have anymore videos where you use phone apps to assist in simple experiments like these? I want my students to begin using their cellphones to learn science.
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)?
Here I was calculating all the force components relative to each other and all I had to do to find the coefficient was plug in the TANGENT OF THE INCLINE?!? *flips table*

So this is way more though out for explaining but I'm still confused. I've been given a measure an object of 400g on a protractor of 20 degrees and an equation of sin/cos = u What's the coefficient of friction if I have no other measures to go off other than just an angle. Am I missing something here?
I do not understand why you are asking this question. Your question is answered by this video. That is what the video is for, to answer the question you are asking.
@@FlippingPhysicswell I don't want to say I'm a dunce but just utter confusion over the problem at hand. Physics is the weakest part of my scientific journey and it gives me complete brain fuzz. The materials I was given, I feel, were very half assed, so though I now understand from this that cos/sin is the answer, I still don't "get it" in that I'm looking for numbers that I don't see. All I have is an angle of 20 degrees which at the point the object started to slide down the ramp. So what am I not getting? No matter how many times I go over it it just isn't breaking through my mind barrier. I have no distances to work with. Am I being an idiot?
In the end, we prove that the coefficient of static friction between the book and the incline equals tangent(theta). The point is that you need to _understand_ how to solve for that.
Those are my children. You are essentially looking at my workplace here and I have adorned my "desk" with pictures of my family. Glad you enjoyed my explanation.
Nice shirt really kept me focused on you during the talking parts of the video. Also nice females in the corners of the board they served their purpose!!!
hey, this really helped with my physics lab thanks, your way of explaining things are very cool!!
You are welcome!
ur wolf is very cool!
This is great! Well explained, silly, fun. This channel deserves some more recognition
I agree
Awesome video! My college physics class was stumping me (especially with friction).
Saweet! Glad to help you figure it out.

I have been teaching physics on the high school and college levels for 38 years. You're good!
Wow. Professor Feynman, I am honored to have your support more than 30 years after you died!

2021 still useful for physics, thanks for the video you helped me a lot.
You are the best physics lecturers ever.
At first i couldnt tell they were all the same people. Kudos man
Thanks for helping me with my phys prelab, Mr P! :D
This helped me SO MUCH! Thank you very much for your videos, and this isn't the first time your videos have come to my rescue
You are so welcome!
U saved my life...thank you😩🥺
You’re welcome 😊
(Hyperbole appreciated)
Very well done!! Wish I would have had this type of explanation back in the 1970s when I was taking physics as an undergrad.
I would have loved that as well.
dude soooo gooood! thank you!
Thank you and you are welcome!
Wow such a great video! Thank you so much :)
You are absolutely welcome.
I'm so thankful I found this channel, very educational
I am glad you found it as well!
Your vids help me so much. Thanks, man
You are welcome mr. starlight!
Hahahah you had me cracking up at the song "Everybody brought mass".
Great! I hope it did not distract from your learning too much. 😇
Any plans to drop this fire?? 😂
Wow, this guys is great, and super funny. Bob is chill!!
Thank you!! I'll pass your kind words on to Bo.
Thank you!
"got it in my notes.. somewhere" LOL he never takes notes!
He also never wears shoes.
You sir are awesome
These are some great videos!
Thanks!
Great video. Thank you.
Bobby the whole video😮
Thank you bro you help me
Best! gonna show to my siblings!!!!

I was wondering why the "mg" cancel out?
very cool.
Thanks mate this video helped a lot :)
You are welcome, mate!
Thank you , it was really helpful.
You have a new sub.
You are welcome. Thanks for becoming a subscriber. I hope you can continue to learn from my content.
how did you keep your phone up while moving the ramp?

Hey bobby u r great...!!!
Keep it up
I really support your system of teaching and learning 😊😊😊
Thanks. Are Billy and Bo doing okay as well?
I am learning with them 😁😁😁together....
Even makes learning better with them
Good job Dear
That is awesome. Glad you are learning with my students!
He he....!!!!
Keep it up Sir
Incredible!!

*flips table*
i was thinking the same thing 😂 i know some people need to explain their work but i just need the basic part lol !
Good stuff here
Thank you!!
You are welcome.
what would the dependent variable be in this experiment?
Loved it!
Great!
Which application you used to find angle of inclined
It's the default iOS compass app. Swipe right for a level.
Flipping Physics thanks
I have a question. Would changing the mass of the object affect the critical angle?
my mind is blown i finally got it at 1:30am because of this thanK
I hope you got some sleep!
what app did you use for measure degrees? greatings from mexico! xx

@@FlippingPhysics haha this comment did not age well
Sooo Good!!
THX!!
after finding the coefficient of static friction , how do we find the normal force ? to find the normal force?
good stuff
Glad you think so
Sooo how much force would be required to push a 100kg object up a 12 degree incline?
How can we improve this experiment to find the coefficient of static friction between two surfaces? Please respond, anyone! Thanks in advance

@4: 10 why did you use mgsin(theta) instead of mg?
+Donal Moloney I have a video which explains that. www.flippingphysics.com/incline-components.html
I saw a problem like this when I was studying for the FE exam
So Impressiveee
Thanks!
The effect of gravity is weight and points directly down, not at a right angle to the slope.
Agreed. Please see: www.flippingphysics.com/incline-components.html
you just saved my lab grade
I hope so!
Im the student in the middle in physics but the student on the left in chem. Thank you so much for this video I hate physics so muchhhhhhhh!!!
Sorry to hear that. I hope I have mitigated some of that hate.
I’m so confused. Why isn’t it just tan(theta ) what was the point of everything else
In the end, we prove that the coefficient of static friction between the book and the incline equals tangent(theta). The point is that you need to _understand_ how to solve for that.
is the coefficient of static friction always equal to tan theta or just in this case?
Just in this specific case.
goat
Could you state some errors or assumptions in this lab
How about this: www.flippingphysics.com/uncertainty-mu.html
Flipping Physics are there any assumptions made during this lab?
god i need to drop physics
Who are the 2 girls on either side of whiteboard? Nice explanation BTW !!
Those are my children. You are essentially looking at my workplace here and I have adorned my "desk" with pictures of my family. Glad you enjoyed my explanation.
that's good but u didn;t tell how the inclination angle is equal to the sinO or cosO that you're substituting ....
I have an entire video which goes over that: www.flippingphysics.com/incline-components.html
thank you for not sometimes speaking in russian like my physics teacher
Ich kann ein bisschen Deutsch sprechen, falls das hilfreich ist.
@@FlippingPhysics NO
Nice shirt really kept me focused on you during the talking parts of the video. Also nice females in the corners of the board they served their purpose!!!
interestingly this is the answer to 2017's 2nd frq question
which I got right saying it is equal to tan(theta).(in a practice run this day (in 2018))(that's too many parenthesizes).
Turns out trig has real world applications after all
Of course it does!
Please explain to hindi language
