i have an electricity and magnetism test coming up soon. too soon. and this SAVED ME. your whole playlist. life saving, life CHANGING. thank you. so much.
You're so welcome. Good luck with your test! And if you wanted to practice real exam questions, I've got my own video solutions to two full exams (Paper 1 and Paper 2) on OSC Study
i hope you failed
thank you so much for this video! i was having a really rough week in physics and this video gave me the motivation to keep going- keep making great content- you are very good at explaining the process!!
You got this!
i swear you are a godsend. thank you.
I'm so happy to help!
Cheers, Mitch
Thx a lot
For the caclulation for acceleration why dont we also multiply by 365 days in the Period
Ah, that's because we are assuming the period of rotation of the Earth is about its own axis (what we call one day, so 24 hrs). I didn't need to account for the Earth making one complete orbit around the Sun (if I had, then I WOULD have needed to account for the period of orbit being 365 days as you mentioned, rather than the period of rotation that I used of 24 hrs). Hope that helps!
@@OSC1990 Oh that makes sense. Thank you !
I want to know the app u are using
For drawing? Baiboard for iOS. For recording? I'm using Camtasia
how do we know that it takes 24h to get around earth? im confused
It takes the Earth 24 hours to rotate about its own axis, so that's one day.
It takes the Earth 365 (and a bit more) days to go around the Sun, so that's one year.
@@OSC1990 oh ok thank you! you're videos are great!
