Friction [IB Physics SL/HL]

[@sergioolijnyk]

YOUR VIDEOS SAVED ME!!! TOMORROW I HAVE AN EXAM AND I UNDERSTOOD EVERYTHING BECAUSE OF U. YOU ARE A GENIUS

[@OSC1990]

I'm so glad you found the videos helpful! Cheers, Mitch

[@angadvirk9516]

man my physics teacher is sooooo bad. I have to teach myself using the textbook. Luckily I found you.

[@OSC1990]

I'm so glad I could help. Good luck with your studies! :)

[@yemiajiteru978]

It is an honour to watch your videos. Keep up the good work!!!

[@OSC1990]

Thank you very much! Cheers, Mitch

[@abdullamarhoon8321]

Nice content
That helped me so much for this year more than my teacher

[@lisasolomey6334]

thank you! Please keep making more of these videos they are so helpful!

[@edwardlittle112]

This guy is such a legend. Showed my class this channel.

[@OSC1990]

Thanks for that, I appreciate it! :)

[@vitoroliveira1332]

thank you for helping me I actually learned something not only how to prove the reliability of a certain formula

[@im3ga525]

Thank you so much! You're helping my IB Physics Prep!

[@OSC1990]

Happy to help! Cheers, Mitch

[@eve_______]

My teacher showed us ur examples at school lol. Please bless us ib student with knowledge while examinations 🙏👍

[@vivanshah7171]

YOU ARE A SAVIOUR MAN! KEEP UP THE GOOD WORK!!

[@OSC1990]

Thank you so much! And you keep up the hard work with the studying :)

[@shalabi569]

I love you mitch!

[@OSC1990]

Hah, thank you! Cheers, Mitch

[@ilikecookies608]

Hi Mitch!, on tme 8:33, shouldn't the Normal reaction force be m x g x sen since its on the y axis?

[@OSC1990]

Ahh. but you have to turn your head to see which way the forces do. The normal force should really be mxgxcos theta in this case.

[@oklunarrk8924]

This man is the goat

[@OSC1990]

Thank you so much!

[@valentinalopezcoronel579]

why do you used the dynamic formula when ut asks the status faction, it must be

[@coolkid9206]

Do u have a vid on potential dividers? cant seem to find it

[@OSC1990]

I don't think I have a specific video on them, but there are a few examples in OSC Study where I solve exam questions and show you how to solve them there with a video?

[@AarushKhirwadkar]

Shouldn't N = -mgcosθ, since it (N) is acting in the opposite direction?

[@eve_______]

Aarush Khirwadkar in this case they just ask for magnitude direction should not bother us

[@aalamsultanji4514]

No, because the normal force and the weight cancel each other out, and for that to happen they have to be equal. Which means that:
N - mgcosØ = 0. Hence, N = mgcosØ

[@pharaxh856]

Aye thanks a bunch :D

[@eddyquansah5451]

if it were for dynamic friction how would we go about that?

[@OSC1990]

Dynamic friction is important once an object is moving. Then you just use the equation with mu_d in it

[@setaremaleki6552]

if the surface is lifted wouldn't the object be moving so it should be a dynamic friction?

[@marcuscheung5025]

It wasn't moving until a certain point

[@ilse_22]

There might be so much friction that the object stays unmoving despite the alleviated surface

[@akmalsultanov3990]

It’s time M2024 students, wish me and everyone else luck

[@OSC1990]

Good luck!
