You're better than my phd physics teacher in school

[@FlippingPhysics]

+Ahmed Ghazi Thanks and sorry.

@@FlippingPhysics cause prof wanted student to fail but flip youtuber wants student to win

[@limagalang]

This channel is the hidden gem of YT. It's not your average monotonous information physics video or the video that has nice graphics but limited information, it's the combination of both.

[@FlippingPhysics]

Thank you. I do my best. It is lovely to know you appreciate my work!

[@Nicholas105100]

This guy is a lifesaver. These vids make physics so much more understandable.

[@FlippingPhysics]

+N1ch0lasRam Yep, that's me. Saving lives!

[@monisharkkk]

timeless explanation!! what an amazing job

[@WeAreShowboat]

High production value. Engaging presentation. Precise terminology and consistent justification of assumptions. You are making some of the most consistently high quality physics education videos out there. Thanks. I can't wait to use these with my students next year. Great job. With the scissors, are you hinting that in the last video in the series you are going to shave your hair?

[@FlippingPhysics]

Wow, that is some high praise. Thank you very much for the kudos and please do use my videos with your students; that is why I am creating them. As far as the scissors, no, I will not be shaving my head. You many not have noticed my many hair issues in the video, however, I did. At that particular moment, there was a lock of hair sticking up alfalfa style and watching the video just made me want to cut it.

[@aeronpauldaliva8709]

This channel deserves more subs. I understand it so so easily.

[@FlippingPhysics]

Awesome. Thanks. (and I agree.)

[@rocks813]

I have been really, really scared of physics, but your unique approach and flow of thought with regard to these concepts help a newbie like me to learn very well! Thank you, Mr. P. I will continue to watch these videos, 50% for fun and 50% for the joy of learning as if I belong to your classroom.

[@ariaflame-au]

Just starting to cover projectile motion with my students and tips for them on how to approach projectile motion problems are always good. Fun and comprehensive. Thanks.

[@FlippingPhysics]

Ariaflame You are welcome. I hope your students find it helpful.

[@billywilliam7747]

I love these video series - the actors are hilarious - great students. I love it

[@FlippingPhysics]

Thanks Dieter! You have left me some kind comments.

[@SK-kn9pl]

this is one of the best educational videos I've ever seen on youtube

[@FlippingPhysics]

Thanks! Keep on learning.

[@thebread9]

This is next level teaching right here. Hope you get picked up by major news someday or something gives you the hype you deserve

[@FlippingPhysics]

Thanks. "next level teacher" is quite a compliment.

[@rijabakhtawar8197]

You're creative and informative. Thankyou for saving the lives of many confused students like me and taking time to make these videos

[@joeymartinez7171]

These videos are momumemtal. A real prize for those in Ap Physics

[@FlippingPhysics]

Rock on! Thanks.

[@morganabbotts]

So more engaging than my physics classroom :(

[@Acecool]

Because he likely has a passion for it; most teachers do not. They become a teacher to get a job, instead of as a career choice. They end up taking out their displeasure on their students who then suffer for it. School as we knew it, is becoming obsolete. I've only ever had a handful of teachers that actually had a passion. I learned Calculus from a fantastic lady in College when all the other math professors just spewed gibberish I didn't understand. She engaged the class and instead of regurgitating the book ( meaning they don't know the material ) she rephrased everything in her own way and if you had a question about it, she could rephrase it a hundred different ways ( meaning she knows the material ). Too many teachers regurgitate and do not deviate from the text in the book; and when we pay for a class, we expect the kind of experience I got from the female professor ( who was a temp / sub ) instead of the experience I got from the majority of tenured professors that didn't know the material intimately.

[@sirrismendozasunlessrealms5775]

You know... this is passion. You sir, have created your own form of art.

[@FlippingPhysics]

This is passion. You are absolutely correct. 😀

[@naseefbro2519]

I appreciate the energy and time which were put in this video

[@FlippingPhysics]

Thank you for recognizing that it took energy and time. Glad to help you learn!

[@FlippingPhysics]

+Ms. Pendleton Glad you are using my videos with your students and they are enjoying them. It is enough currently to create this videos and teach part-time simultaneously, therefore, I am not sharing my resources (other than all of these free videos which I provide).

[@ms.pendleton9537]

[@FlippingPhysics]

That's awesome! Glad to help out a fellow teacher.

[@nurrahmanpurwanto2976]

4:14 ,I think in that environment The Vx is not constant, Due to air resistance the Vx0 (Beginning) > Vxa (At point a), The Vx is constant IF There is no air around the projectile (Vacuum Condition)

[@KitBetts-Masters]

This is brilliant, so funny! ;-)

[@FlippingPhysics]

Thanks. I never know what is actually going to be humorous to other people, so I just try to make myself laugh.

[@KitBetts-Masters]

Ha ha, it works, I guess that's the start of most humour. I need to try and get more humour into my videos I think, but I feel a bit silly making jokes as I'm largely filming on my own. Is it just you filming and making these videos or do you have a squad? Thanks :-)

[@FlippingPhysics]

Here is a detailed answer to your question. flippingphysics.com/making-a-video.html

[@KitBetts-Masters]

Love it! You have an intense workflow! You obviously love Physics and believe in flipping and that comes through strongly in your videos.

[@tumnaharingaek4139]

A projectile is fired upward at an angle Ɵ with the vertical with velocity U. Show that its trajectory is a parabola. Obtain expressions for (i) maximum height attained (ii) time of flight. & A projectile is fired upward at an angle Ɵ with the vertical with velocity U. Show that its trajectory is a parabola. Obtain expressions for (i) maximum height attained (ii) time of flight. Sir what is the difference

[@carultch]

Those look like exact copies of the same problem statement. Only difference I'm seeing is that the angle given is from vertical, when I'm accustomed to seeing these problems specified with an angle from the horizontal.

[@bhawnamehta2261]

At 2:34 , It felt like I'm in my class. I'm like Bo. Forgetting sign conventions and directions and units and the whole class including the teacher, trying to fix it..

[@Mongo_-ju7nw]

Are you sure change in time a scalar? I would look it up if i were you.

[@sue_yang]

I don't understand why the acceleration is zero and the velocity is constant in x-direction at 3:58.

[@jeson6806]

well fit to be a professor in my lecture group

[@FlippingPhysics]

+jeson banda Thanks.

[@fenudyasanding3600]

May i ask, why the motion of projectile is free falling motion? Thank you 🙏🏼😊

[@carultch]

It is in free fall because the only force of significance acting upon it, is the force of gravity. In the x-direction, there is no force acting on it, and it is proceeding in an inertial straight line (top-down view of its path) at a constant speed. In the y-direction, it is simultaneously in free fall with its x-direction motion.

[@goob3581]

thanks so much, really helped a lot :D

[@FlippingPhysics]

+google is free You are welcome. Glad to help.

[@sivakumarsiva1743]

So the v initial in x direction = v final in x direction since it is constant

[@FlippingPhysics]

In projectile motion the velocity in the x-direction is constant.

[@gilangsatriya3027]

it's nice .. thanks

[@suyashsrivastava371]

Sir but the ball moves some distance in the x direction. Since it doesn't fall in the same y-direction.

[@suyashsrivastava371]

can you help me out

[@suyashsrivastava371]

Sir, you can even refer to this website and check that there is displacement in x - direction. www.physicsclassroom.com/Physics-Interactives/Vectors-and-Projectiles/Projectile-Simulator/Projectile-Simulator-Interactive

[@FlippingPhysics]

I am afraid your question is not very clear, however, I will do my best. My assumption is you are referring to the moment at 3:27 when I drop the ball and ask if the ball is accelerating in the x-direction. Because the initial velocity of the ball is zero when I drop it and the acceleration in the x-direction is zero, the ball _when dropped_ has no velocity and hence no displacement in the x-direction. When an object is in projectile motion it will have a constant velocity and therefore displacement in the x-direction. Note: In the above example when I drop the ball, the ball is _not_ in projectile motion, it is only experiencing Free Fall.

[@suyashsrivastava371]

Sir as you said that the velocity in x direction will be a constant value. Can you Explain this further

[@suyashsrivastava371]

Sir I must Say that you are a good teacher.Back here in our country not in all schools but in my school and a few of them we are taught just theoretically.Rather than teaching us how to use what we study to solve daily life problems.Although my schoolmates are able to solve all the toughest problems but they do not have an experience in doing stuff practically.

[@mustafaRoya]

Thank you sir

[@FlippingPhysics]

+Gholam Mustafa Ali You are welcome. Thanks for all the thanks!

[@sivakumarsiva1743]

Please reply as fast as possible o have my exams tomorrow . Should'nt it be -0.087 since displacement os negative
