I was now a 2nd year medical student. 3 years back i watch your videos and suddenly today i remember the iconic "flippppinnnggg physiiiiics" intro and i am not disappointed to see it again after years. Thanks again sir , without you i cant enter med school and love physics

Thanks for rubbing it in

THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Worst explanation ever.

Brilliant. Used this with my AS Phys class today and we loved it. Videoing Meldes experiment and the animation of interference really gets the key points across clearly. Thank you, your production values are so advanced.

Except if its in an ocean and you're a politician bent on increasing carbon tax😅

Remains the same

Three states these nuts. H20 water by definition when fire is added breaks apart into Oxygen and Hydrogen...no longer water as the heat does not allow for rebinding of structure until the visible particles cool on a surface and collect oxygen to form water again. For the genius whos going to say that greyish white is water vapor obviously doesnt understand that oxygen burns transparent...so you'd only see the bubbles of collecting Oxygen in the water before it hits the surface and pops sending out the Hydrogen vapor. Look up oxygen fire if you don't believe me. -Abéràk SamUéL Lï Santana DrácûL Former Dr. JACKAL

Thank you for this explanation! Thank you so much for acknowledging and addressing the math components too! i had the same exact questions the students had. I am taking an advanced physics course but have not taken geometry yet so I am at a bit of a disadvantage when it comes to angles and trig functions. I am happy when physics teachers take some time to address the geometry components so everyone can be successful.

So you're saying global warming is a lie?

Wow, that's amazing! Will you be creating an AP Physics C Ultimate Review Packet? That would be awesome. Thank you for all your helpful videos!

love it 😊 <3

thanks for ur great explanation

Is this fluid mech?

Great video! Peace out

**For anyone confused:** Ice is less dense than water, so when it melts, the water level should rise. But, some of the ice is above the water. The volume of ice displaced is equal to the volume of water it will turn into when it melts (pV=m). So the water level does not rise.

wow amazing teacher thank you so much teacher for ur good work hope u have a good day

Thank you so much for making these videos. I am so happy I found them, and I purchased your Ultimate Review packet, and it is very good!

Can I use delta Y =Vyinital (t) +.5(a)(t)^2 instead of the intial formula you used? I still got the same answer.

The right hand side of the Work-Energy Theorem says change in KE but that is incorrect because the velocity you used was the speed of the COM . In reality each of the individual forces that make up the 'Net Force' will have different displacements in the direction of those individual forces . If you summed the product of those individual forces and their displacements (in the direction of the forces) that would be the real work done on the system. Using the displacement and rate of displacement (ie. velocity ) of the COM only works if the 'body' is regarded as a point particle . Therefore that is your big assumption and the right hand should be regarded as the 'change in kinetic energy of the COM'.

you are a life saver!!!

Yep

my teacher linked this video to a joke problem he assigned us and i skipped to the middle and was terrified

So why are the, global warming fear mongers, always talking about sea levels rising?

So the glaciers melting won't flood the world. Gotcha

❤❤❤❤❤ thank you teacher

Bobby - that was gerat - thank you for creating this! 🙏 I really enjoyed learning with you too!

I got you G

god bless you

absolutely brilliant you deserve global funding from the all countries' education funds allocated to their government

We are not worried about ice in the oceans melting. We are worried about ice on land melting and making the oceans higher, a thing that has absolutely happened in the past.

For the projectile motion, why do the adjacent and opposite sides get assigned subscripts, is it purely for the equation, or is it the direction?

This video is not helpful at all unless, of course, someone has already taken physics. What about the novice who has never taken physics? This video doesn't tell you how these equations were derived? What is the purpose of these equations? They just popped these equations without any explanations at all. Why do a didactic video without a detailed explanation of every step?

I thought it would go down because ice expands and takes up more space, so when it melted it would take up less space overall.

Thank you so much ,I struggled understanding this force my entire highschool year ,but i think i finally got it If only teachers would explain forces like this,sometime demonstration do the work 😊❤ 3:09

Youre saving the semester

I'm kinda worried about the 2025 Mechanics exam cause they changed the MCQ style to be much more comprehensive and 'theoretical'. (Use to be kind of a plug and chug test with numbers here and there, while now it's 75% situations where we pick the most accurate statement that involves some physics law or equation) Have you heard anything about the upcoming test and are there any resources that could help with this worry? I've been taking the past FRQ's they post and I kind of have them down... just the MCQs that kills me lol!

12 hours until i leave for my unit one exam.. thank u!

This is really great but I probably should've watched this sooner rather than hours before my exam 😭

This is the much clearer explanation that they do on AP daily videos, well done!👏 I'm waiting for the moment you will be featured on AP daily videos:)

so if i'm keeping track... h= [(kxi^2) / (2mugcosθ+2mgsinθ)] sinθ

Let me appreciate you professor ❤❤❤When I first watched your video, I found really complicated and lost but I gradually starting to understand and I think I'm not afraid of physics anymore. The Questions and Answers environment during your explanation is such a treasure time❤❤❤❤

Very funny and helpful! Thanks! ❤
