i´m spanish aircraft engineer and for me you explain with more relation the concepts and all of them in a summaraized way than spanish teachers . greetings since spain.
This tutor has gotten me through engineering, trig, geometry, pre-calc, calc, physics, and chem. I just wanna say ty for saving my entire hs career. I will see you in college o7
struggling to understand powerpoint presentations just left for us to study... your videos literally saved my grades. Words cannot express how thankful I am for your channel
Droppind a comment for the very first time. I want to say a big thank you. I watch your videos before I read my lecture slides and more than 5 times I have seen the examples u explained vigorously written as ununderstandable points on my slide. Thanks a lot you are very much appreciated
People don't understand momentum! Here is my explanation. Momentum is the sum of all the sub masses times the velocities of each sub particles together of that object! If you understand that then you're golden!
Um, I do wish I was a lot smarter because I want to understand these physics concepts due to my simple curiosity about things. I am just not catching on, yet.
Its not your level of smartness that is making you not understand. Every human has the same ability to learn. You just need to be exposed to as much physics as possible. Watch documentaries and read beginner level books. Usually, watching or reading the history behind the concepts helps you to see the reasoning that guys like Isaac Newton used when coming up with these ideas. If you have a solid understanding of fundamentals, everything else will fall into place. Like my professor says, every physics test after your first one is cumulative. If you don't understand something, something is wrong in your foundation. Just go back a bit and practice some easier ones. Everything is easy once you get good at it.
To understand you probably need to play around with the formulas. Take the mass to the other side, and try to see what it's saying, replace the next round with the velocity, or conjure another formula out from another dimension (F = ma) and try to find as much meaning as you can. 😗
For the last example, how there is no external torque? Is not the weight of the box pointing downward perpendicular to the rotating sarface? So Torque =Fr, which F=mg and r=distance from center to the box ?
I think it's because you're defining your system here as being both the box and the surface. If you just defined your system to be the surface, then it would indeed be providing a net external torque.
The weight of the box wouldn't really cause any turning effect. If u see it practically, if u pushed the disc downwards with the box or your hand it wouldn't rotate The force is parallel to the axis of rotation, so it would cause any turning effect If u consider as a whole single system then the T would be zero
That is thrust or antigravity by any type had enough power from electricity current or rotation of blades or spindle of protruding knobs ...in ufo design failed because invert space push back so if the center of ufo is hollow then it can travel up or foward
The net external toque is zero, but there are internal forces, and correspondingly torques involved with redistributing the mass. Their effect adds up to zero on the system as a whole.

This is the most underrated tutor channel on youtube ffs
nah man he has a mass cult follower
Jaden and Murray totally aren't the same person lmao, idiots
After 2 years, he is not underrated anymore. He almost has 3 mil subs. He is the best!
@Jaden Dexter bots
@WireTrap a good man certainly🙏🏼 hes carrying my studying for this final tomorrow!! As per usual tbh
Everything you do on this channel is greatly appreciated. Thank you!

Did u have Jeremy adlemen for ur physics teacher?
This tutor is best for me. I RECOND and RELY on his videos. He shows compassion and dedication when explains. THANK YOU SO MUCH and GOD BLESS YOU.
Dude ur genuinely the GOAT of tutoring
Almost every video you make is easy to understand. BEST ONLINE TUTOR EVER!

Best tutor ever...you have really helped me with physics
Straight to the point! Very helpful.
Thank you for taking the time to make such a helpful video. I hope a lot of people get to watch it.
Oh wow, i did not make the connection between linear and angular before😂 makes much more sense now. Thanks!
Amazing explanation i hope u win a award for this
Thank you for your great explanation on these difficult concept you make it seem so flawless!!!
Am gaining a lot from this person may God keep on blessing u ❤
Usefully system of teaching the overall system of lessons
Thanks for an amazing, informative video!.
Your chemistry is very awosme
GOD OF TUTORS
You are all rounder thank you so much 😊☺️

THIS. IS. GOLD.
This guy is a genius
thank you for teaching me physics, math, python, chemistry !!! :)
لما انجح بالتوجيهي ان شاء الله، رح اهدي نجاحي الك يسعد اهلك 😂🤍
my teacher speedrun our ap physics class in 2 weeks, tmr is the big test and we havent touched any problem for 3 days.
Thank you very much. It was well understood. clear and concise
❤thanks bro
thanks man god bless you
Thank u mark whalberg
great explanation bro. thank you
Thank u sir XD...
Thank You!❤
I love you man .

Search Walter Lewin, his lectures are visual, so maybe that will help. He does great work!

I am not a teacher though.
Finding a good teacher could also help.
thank you
why is it so good?
thanks po irreg na ako
you're god man, thanks.

Thank you so so much
What would happen if there was torque slowing down angular speed. How would to find time it takes for angular speed to reach 0
find the impulse and time
Net torque is equal to inertia times angular acceleration. Once you find acceleration, you can use v(initial) + at = v(final).
OChem Tutor and bowtie bizen are the best teachers
An unknown portion of Organic Chemistry
Well explained thank you
That is thrust or antigravity by any type had enough power from electricity current or rotation of blades or spindle of protruding knobs ...in ufo design failed because invert space push back so if the center of ufo is hollow then it can travel up or foward
i love you.
If net torque is equal to zero then why isnt it at rotational equilibrim and have constant angulatlr speed??
The net external toque is zero, but there are internal forces, and correspondingly torques involved with redistributing the mass. Their effect adds up to zero on the system as a whole.
By slow talk in simple words, you are convincing the concepts otherwise difficult to understand.
ok now understand 😭
We battlee beyblades on our physics subject
So ya have a New York accent?
I want to see your face tutor
i wanna know what you look like
go touch some grass, bro
