holy crap, do you realize how amazing your teaching style is? You are giving me a genuine understanding of the formulas I have just been plugging numbers into for class!

All college physics 1 lectures need to be replaced with your videos and the money given to you to make videos for all of physics!

I started taking AP physics this year, and man, when throughout months I had no understanding, which turned my interest to dust in physics. Every day, I was on the verge of giving up, which then turned into frustration and indifference with the subject. But you, you, are changing that,

[alphalopez]

I just failed my first quiz in physics because i don't know how to translate my fbd into a solution then came back studying because as we go on in lessons, it always have these forces. Now I clearly understand it. Thank you so much!!

This is the 'awesomest' tutorial videos i have seen on youtube now. The speed is neither fast nor slow. Furthermore the way of representing of the material is very entertaining thus more likely for a student to remember it. And yeah, 'awesomest' is the word that fits best haha!

Let me introduce you to your Numbers Dependency and our Equation Holster! Shall we apply our 5 Steps to Solve any Free Body Diagram Problem to an Introductory Tension Force Problem? #PhysicsED #APPhysics1

"Equation Holster" -- LOVE IT :-) I am going to "acquire" this phrase :-)

[ethanlay]

I'm a high school senior in quarantine and I am learning so much from your videos. Your videos help me in my physics class so much !!!!

[nicolasdecicilia]

u r a genius..I practically spend years watching math and phys videos..and I think u r unique

[IZeoClass]

Bro... bro/// I need this teacher. Fun, entertaining and explanations clear as water... then boom! the punch line with that device...

[shashijayasuriya]

Excellent as other teacher understands the way student thinks as teacher ever....

[jawspeak]

This was amazing. I took this years ago but forgot a lot and needed this. Love the reminder about the normal force - I missed it and the example mistake in here really helped my understanding.

[dougaldmactaggart]

you are a great teacher. I think a really great short video to cover would be:
If two people are pulling at either end of a rope with 3N, what is the tension in the rope. Once I was told the answer to this my intuition of what tension means was enlightened!!

[mpmaniac]

You are an excellent teacher! Thank you for making these videos!

[TotalDrganMania]

Is nobody going to say anything about how Bo solved .155 times 9.8 over sin28 in his head? Lol

[pukamon]

Your videos are awesome, and it's helping me learn a lot more watching your videos than going to class.
Why is it that you only find the x and y components for the forces that are at an angle i.e. Ft1? It's intuitive that Ft2 and Fg lie on the x and y axes, but how come they don't have the horizontal and vertical components.

[samiulhaquerounok]

Sir, Excellent class I have ever seen, I earnestly beg to you for marking videos about theory of relativity

[rigobatiancila]

5 years old but still helping me more than my teacher who taught tension forces a few minutes ago.

FLIPPING PHYSICS I LOVE YOU VIDEOS< }

[ABIYSCGSTEGD]

Great video.  Also entertaining.  It would nice if you left a few frames of unobstructed view of the board at the end so that we can pause it.  It would be nice to see the whole solution in one shot.

8:50 Mr. P, does it matter where on that string you hang the mass? Perhaps in terns of torque?
