Thank you kind sir

Thank you Mr Heinrich. Subbed 🗣️

Can someone please explain to me why the units work out to rad/s rather than sqrt(rad)/s. Isn’t cos theta also under the square root?

4 years and still you're saving lives thank you for this

Just saved my life. Thank god!

pls can you either record horizontally or make the screen bigger so that we can read the whole text? Super useful videos otherwise!

🐐🐐🐐🐐🐐

5 am and I found this. My day is saved!

thank you so much for all of these videos, i was out for a week sick and they are really helping me catch up

Thank you so much for this! I found it really helpful

The key that is provided to teachers by AP Classroom says the H.A. is R/T^2, and the vertical axis is tan(theta), which I could not understand. Thank you for confirming my suspicions!

I love you

This helps sooo much

uhm so where do i find the correct answers for part d)?

can someone explain why in part c) the upward velpcoty at position 2 and the downward one are equal? I didnt quite get what he meant.

the goat

If Branch B gets 12 amp current that means branch A also gets 12 amps of current in the orginal circuit. However would that not conflict with the loop rule, as the loop created with the battery and branch A do not add up to 0?(80 volts and -60volts dont add up to 0)

Thank you so much sir (୨୧•͈ᴗ•͈)◞♡ Wish you the happiest physics journey~

THE GOAT

In what case would the center of mass be speeding up?

You have to square root the answer for question b 5:17

Ths vidio hilping me so much rthanks. you!!!!

Thanks

On the ap exam, in the questions like part d, can you take down as positive? Do you need to announce it somewhere before doing it? Because I've done the constant negative slope for v graph and straight line on -10 for acceleration

good stuff, thanks so much man

if you see this comment i just want you to know that your work is greatly appreciated. unfortunately i wasnt lucky enough this year to get a very good physics teacher and reviewing these videos has really helped me to fully grasp the concepts, and the way you explain things makes all this information much easier to digest and understand. hope you enjoy teaching

Figure*

For part bii, couldn't you just do F=ma F=mv/t v=Ft/m v=(2.4N)(0.5s)/(0.4kg)

This dude is the goat

Really helpful, but I can't seem to find the second part to this FRQ.

shouldn't it be an elastic collision because it's a bounce?

I love you ❤

bro I owe you my life thank you so much i want to name my children after you

Thank you so much

This guy is great

Heinrich is the goat

I'm a bit confused about part C. If you use the equation or displacement (yf-y0= v0t +1/2 at^2) and since displacement is 0, if you solve for t, you end up with t= 2v0/g. Why would this answer be wrong?

I love you

For part a ii) why wouldn’t you include tension in the FBD?

i have zero idea how i would pass without you 🙏🙏 common heinrich W 🔥

1/19/23 MS.Blach class period 4 Gracias me amigo.

W Mr. Heinrich

Why there isn't a normal force acting on the block?

3:55 lol

physics? more like physically about to fail my class.

I love this guy

do you do online tutoring

could you also use t=sqrt(2h/g) and substitute the hmax equation (vo^2/g) into the time equation and get vo/g?

thank you
