- Grade 11 Newton Laws: Objects on a slope
Do you need more videos? I have a complete online course with way more content.Click here: purchase.kevin... 🟢Follow me on Instagram: / kevinmathscience
You've actually managed to make me excited about doing physics, thank you ❤️
Wonderful Jordy! All the best for this year.
Keep lying to yourself

Dude I have been watching your videos since grade 11 now am in matric all thanks to you .I hope you get enough credit for your work and thank you for all the knowledge you're sharing with us ❤️❤️🙏
It is a huge pleasure and so happy it has helped you :)
Carried me in grade 10 and looks like you'll be carrying my grade 11 aswell
And 12 for me🎉
For the first time in my life I now understand Newton’s Laws . Especially the Second Law . Thank you so much Sir . May God continue to bless you.😭🙏
You a legendary tutor sir thank you so much
Pleasure!!!
I honestly want to meet you Kevin and shake your hand, you've been more of a teacher to me for the past 5 years then my school teachers
Actually studying for a test im writing tomorrow, for once i feel confident that ill pass, all thanks to you ❤
You helped me understand newton's laws...for that i thank you❤
Thank you very much❤️ I actually understand better
Awesome Shuvai! Glad you understanding the work.
Thanks for the teaching u helped to understand physics ❤
hey Kevin, there's a tutor my school brings in on Saturdays to help us with physics and he's a marker for the end of year matric papers. he mentioned that we should add fgparallel and fgperd as solid lines on our freebody diagrams instead of having fg there however our teachers do it the way you do it. so as a matriculant i don't really know what i am supposed to do. my teacher said that i should use her way when writing our exams but she doesn't know about the end of year papers.. what do you suggest?
Imaan, I can promise you that the final exam memo allows for multiple options. You can use the Fg// and Fgperp method. OR you can use Fg as a vertical. The only thing you may not do is use both methods at the same time.
GOD i love this guy and his way of teaching HAHAHAHHAHA sometimes he talks casually like hes reading our minds which makes it both entertaining and fun.. i love it
JESUS LOVES YALL HE SAVES HE IS KING HE IS COMING BACK SOON REPENT RUN TO HIM HE LOVES YALL
@7:21 when i type it into the calculator i dont get your answer
Ohhh nevermind i didn’t put brackets at the end of sin20
😭❤Dropping my tutors for your online course if this goes well tomorrow
Hey Kevin. There's something I really don't understand when it comes to that part of choosing a direction. Do we just choose any direction or there's something we follow before choosing a direction?
Choose any direction u like but commonly use the direction which has the most information makes life easier
on the last example, how did we know the friction is 20? and do we not have to indicate the normal force on the free body diagram?
I'm gonna name my kid Kevin. Thanks man
Haha love this :)
Hey kev genuine question why did you subtract when calculate for the acceleration using the fg perpendicular and why didn't you make the 9.8 a negative because my teacher told it's usually a - 9.8 or is that wrong
So l want to know do you subtract or add when you use fg perpendicular included to calculate acceleration
Hey kevin .
I want to work out force f but i have 2 unknowns please help😭
This is really helpful
Thank you
You're welcome!
Thank God for kevin
Thank you Tinashe! All the best for this year :)
How did u calculate the acceleration
"it is a sin to go to a parallel universe"
Thank you so much!
When do you use sin
Hey Kevin can you do a vid calculating the magnitude on the inclined plane
Why is it up the slope? Kevin
Thanks man
what about the weight of the object?
Hi kev how do u handle an object with two tension forces😢
Please teach how to find the Normal force
Coming soon :)
Zakhele,
I remember now that I already have a normal force video and hope you found it :)
ruclips.net/video/7YhkjSlxsrc/видео.html
I know this was a month ago.
Oh sorry I didn't notice, but thanks anyway.
3:36 I dont get it... sin is supposed to be for the length further from the angle and cos is supposed to be for the length on the angle...?
oh I get it now.... you need to form another triangle on the lengths mg and F(perpendicular) with a 90* angle and a 20* angle, its a shame that its not in the video, it would have made it much more intuitive.
Hello :) I purposefully leave that out most times unless I have a student who is very curious. Reason being it sometimes causes more confusion and they do not expect you to show this or know this in exams. It is easier to always remember that parallel is sin and perpendicular is cos.
I have found that 99% of students prefer that.
where did you get the 9.8 of Fg parallel?
It is always 9.8 for fg, fg parallel and fg perpendicular :)
You are de best❤🎉
❤
Hey Kevin why was your friction =10?
20 I meant
If you look at the diagram, you can see that the Is a force of 20newtons going down the slope
For me to get an answer of 4.65m/s/s, I had to make the objects mass 3.74kg. Am I missing something? :/
I was confused too ,but I got it now. Say Fapplied- friction then - fg parallel
Why didn't you apply frictional force i don't understand 😢
Uncle Kevin, I would truly like to thank you for saving me 😅
somebody tell me why we have this in 9th grade
Hey kevin.
I want to work out force f but I have 2 unknowns please help 😭
