1 hour before the exam!! This is a lifesaver! I finally understand it all

Different surface areas so different amounts of work are done against friction therefore different amount of kinetic energy lost

watching this 3hours before lmao

Damn, you have some massive forearms

exam today gl everyone

Night before revision gang🎉🎉🎉

YOU ARE WONDERFUL

here on the day before physics paper 1 2024!

I love this question. I have never encountered such a peculiar yet interesting question.

🤯

thank you you legend

hello can you please make pdf of past paper relating to this topic or point up some website which makes topic questions on it i want a lot of past papers for this topic , thanks for hearing out

thanks!!!!

This is of igcse not gcse

Thanks a lot

Thanks a lottttt u r the best teacher 🎉

Sir, you’re fantastic. Never thought I’d find a channel more useful than freesciencelessons, especially 1 month away from exams. ❤

8:14 where did you get 10.11 from?

Wow. You’re seriously underrated. Like VERY underrated. I hope your channel grows the attention it begs!! You’re awesome dude! ❤ By any chance, do you teach chem and/or bio? Would be great to have this playlist with those too, if you can!

gcse physics will be the deatch of me but i believe u can get m a 9 :)

For the question about the kidneys, the speed of the ultrasound wave will actually decrease not just because of refraction, because some waves can increase their speed due to refraction. In fact, since ultrasounds are mechanical waves, their speed decreases if they refract from a more refractive medium to a less refractive one. Here the ultrasound waves is going from ceramic (very refractive) to the kidneys (which are less refractive) and as a result their speed decreases. According to the particle model of matter, solids tend to have more packed particles that can transfer sound wave energy faster. The opposite is correct for an EM wave.

Exercise 10: White light will diffract into its constituent light waves in the prism. Since all EM waves will propagate in the same speed in the same medium, then option B must be wrong. The speed of EM waves depends on how refractive or optically dense the medium is. However, since both blue and red lights will have the same speed in the prism, and as speed = wavelength x frequency, therefore the wavelength and the frequency must be inversely proportional. The higher the frequency of an EM wave, the smaller the wavelegth. Since the blue light tends to deviate more towards the normal, then its frequency should be higher than that of the red light. As a result, options A, B and even C should all be wrong. However, option C says "frequency change" and I have no idea what that actually means. Because the white light already contains the blue and the red lights and each doesn't change frequency when it emerges from one medium to another. Anyway, I would still go with option D here. I would love if anyone can comment. Thanks

yo zgcse ik u might not see this but i got the intermediate olympiad in 2 days. Your genuinley the goat. literally like a golden ticket handed to me to pass. WISH ME LUCK :)

These are great thank you so much Zphysics! Just curious how do you say ur name?

Thank you so much, I'm really learning a lot from your videos:)

would you not need to talk about the density of the object?

Sir, could you say that they had different starting points so one may have experienced greater air resistance?

Saving questions I found hard: - 5:27 - 10:11

TYSM!!!! ur voice are so clear too>>> I will suggest your channel to my friends!

Couldn’t 4 - 6n be further simplified to 2(2-3n)?

Which paper pls someone give me name and code which year

this is extremely helpful, really is helping me so thank you so much

Can you do more 6 mark questions like these? Secondly, do you have some physics websites you can recommend? Thanks

Any tips 2 revise physics as its my worst scinece and would ❤ a grafde 7-9

I don't know if you'll see this, but did you also have to mention the horizontal forces?

Hi, I'm just commenting to say many thanks for this video because I do struggle quite a lot with P4- electric circuits. I saw some other parts of your videos, so i was interested to see this. Hopefully this helps, and I'll use this for mocks aswell and let you know how it goes.

Thank you so much! I have always been a grade 9 student but electricity and topic 6 have been the hardest so far!

imo, electricity definitely the hardest topic so far 😢😓

Amazing vid! How would you recommend revising for the required practicals? Additionally, I always struggle with the 6 markers for the GCSE exams - do you a specific method or tips for how I could possible start achieving full marks? Thank you in advance.

Hi, could you talk about how speed is a scalar quantity therefore it has size only and therefore velocity is vector so it has magnitude and direction?

Hey, do you have any vid on waves and can you please do a past paper walkthrough on IGCSE electricity and magnetism please? I have an exam soon!
