So the topic in this video wasn't explained by my professor or the textbook, I just got to figure it out on my own, including that "we go with the plane if the plane is at an angle" at around 1:30 ish. Not explaining it is like a math teacher not teaching notational conventions for a particular mathematical manipulation. Imagine getting a Sigma sum problem with no instructions. Maybe you can figure it out when you see enough of them, but how does it help the student to try to divine the rules of notation and convention by trial and error? Thank you for taking time to explain the "notational conventions" of physics! It should ALWAYS be taught this way!!
Thanks. It never really occurred to me that this concept is actually not explained in any textbooks I have seen. I base the videos I make off of what works for students learning, not on textbooks. Thanks for noticing!
Not really. The reason to break forces into parallel and perpendicular components is because the acceleration in the perpendicular direction is zero and therefore the net force in the perpendicular direction is zero. This is not really applicable to torque problems.
The short answer is, No, this is not applicable to torque problems. The angle measurement in torque problems is generally very different from what I have outlined in this problem.
Still struggling with this concept, couldn't you just flip the diagram to make the acceleration on the x-axis, and since the force of mg moves to the left, the angle is on the y-axis, so may (or 0) = mgcostheta and max = mgsintheta
In this case, would the magnitude of the force normal be equal to the force gravity or to the perpendicular component of the force gravity? Also thanks for your videos, they're the reason I can understand Physics and the maths behind it!
+Lïon Heart I explain the answer to your question here: th-cam.com/video/XO2V1Spfu-4/w-d-xo.htmlm25s Also, you are welcome for the videos. In my opinion, understanding the math behind the physics helps you to understand the Physics.
Glad to help you out. Just so you know, you are not alone. I find that many students struggle with the basic math of the angles and therefore think they do not understand the physics.
True. And I never asked you what you thought of the AP 1 exam results! I guess that author in my prep book was right about everyone being unprepared for the exam.....
+MopTopRock Honestly, I hadn't looked at the results until just now. Only 37% of students received a 3 or better? That's a pretty rough start for the AP Physics 1 exam. According to www.totalregistration.net/AP-Exam-Registration-Service/2015-AP-Exam-Score-Distributions.php "AP Physics 1 was a new AP course and exam this year, with nearly double the number of students who took AP Physics B last year." I think students and teachers were unprepared for how difficult a course AP Physics 1 really is. This is exactly why I teach the way I do; students have to _understand_ the material not just _memorize_ it.
You break forces into components (including the normal force) whenever they are not directly in the two perpendicular directions you are summing the forces in. Here is a good example of when you do _not_ need to break the normal force in to components. www.flippingphysics.com/car-hill-force-normal.html and here were you do have to break the force of tension in to its components. www.flippingphysics.com/conical-pendulum.html
Eureka!! I finally Broke the "SOCK CODE" ... it's a binary code... with Pink sock = 1 and Orange sock = 0 .. and the yellow socks are of a value equal to their nearest Neighbor that is NOT a yellow sock...... it's a 6 digit binary code.... sending encoded messages to Einstein..... :D .... or not ...
After a lot of hard work on this topic.. I finally found your video and my doubts are crystal clear! 💌
Wonderful!!
I was inclined to watch this video.
+TheWarhammer I am disinclined to reply to your comment.

You are the king of physics.
such a marvelous video! It was a pleasure to learn from you!
Thanks!
Does this concept of breaking forces also work on torque problem when the force is at an angle theta from rotational axis?
Not really. The reason to break forces into parallel and perpendicular components is because the acceleration in the perpendicular direction is zero and therefore the net force in the perpendicular direction is zero. This is not really applicable to torque problems.
I am sorry I didn't get it. Please elaborate, sir.
The short answer is, No, this is not applicable to torque problems. The angle measurement in torque problems is generally very different from what I have outlined in this problem.
very helpful.thanks
You're welcome!
Thank you so much!!!! I finally understand this concept! Thank you! :)
That is great!!
Nice dissolve.
Still helping, continue your work

I love you man, all four of you for this video
Love you too.
wow, this is the best video for me. Thank you so much.
You're very welcome!
marvellous video...thank u sir...it helped me a lot
You are welcome!
I guess it's for physics starters. When would you be moving to chapters like Fluid mechanics and waves?
Thankuuu u really made it Easy for me to understand.. ❤️❤️ thankuu so muchhh
You are very welcome!

+Flipping Physics Thank you!
I LOVE YOU AND YOUR VIDEOS
Thank you for all the love, all the positive comments and your subscription. It makes me happy to know I am helping you learn!
U R THE BESTTTTTTTTTTTTTTTTTT
i struggled in physics 1 bc of angles 😔🤚🏽 thank you so much
Glad to help you out. Just so you know, you are not alone. I find that many students struggle with the basic math of the angles and therefore think they do not understand the physics.
Sir please do fluid mechanics. 🙏 God bless you sir
Nice product placement! ;)
+MopTopRock Why not?
+Flipping Physics haha its just funny to me! btw I'm taking physics C mechanics this year ! definitely more mathematically complex than ap 1
+MopTopRock Definitely. However, I find it much more interesting and understandable with the more complex math.

Sir please tell when to resolve normal force

Wtf does this even mean my physics teacher made me watch this and I’m stressed 😭😹
Thanks

+Philip Y Dude, really? Their just socks.
that was my second guess...
They're. :)
im the 500th to like, and the 50th to comment. wow. also great video
I just love u
❤️
Lol I have that book!!
Me too!
He looks like some ticktock guy I saw
