[@Ayah.ngidii]

Mam can you please do more grade 11 maths videos according to the ATP please 🙏

[@DaliaMasood-i1l]

can I say that you really saved me? you 're the best physics teacher in the KZbin. i was very lost in lessons that talk about force you made it easy to me. take this hug from your new student 🫂🫂🫂. thank you a lot 💗💗💗.

Hi ma'am, love the content. Just had a question for the answer of Fn, is to not equal to 17.46N?

Thank you soooo much mam, you have helped transform my marks to a distinction in physics 🫂❤

14:18 why is it minus and not positive??😢

[@DaliaMasood-i1l]

because the normal force and weight are in the opposite direction so that the weight is - and we should add normal force with weight and - times plus equals - so that we subtract. I hope that you get it.

Ma'am, where does one find all the definitions for grade 12?

[@GrannyKelly07]

Most exam guidelines have them (on the internet)

Quality setting is not available

[@missmartinsmathsscience]

That's weird 🥺 from my side it automatically plays in HD quality. Maybe try and watch using wifi, not data or try on a laptop instead of a phone x

[@mianmuhammedmudasir3432]

Quality of video is bad in this video😢. Mam u teach very will i love ur explanation but video quality we cannot change. Please can u fix it

[@missmartinsmathsscience]

Hello! 💓 thank you for saying that however I'm not sure why the quality is bad for you, I just checked and it's perfect on my side if I watch on KZbin. It may be your settings or may be happening if you're using data. I'm not sure how to help fix it because from my side it's fine 🥺
