Thank you very much...I've been battling with moment calculations for the past two years..😢..thanks for making it seem as easy as pie... you're a good teacher 😊
I tried to understand these concepts for the last 2 weeks in class but failed to understand but after seeing this video I understood it better. Thanks a lot sir it really helped me🫡🫡
6:51 for this question I just did F X 3 = (2 X 80) - (4 X 60) + (6 X 90) and I got the right answer too (they both work out u can do + 2 X 80 with F so u basically take it to the other side of the equation or u keep - 2 X 80 on the same side)
What abt this question A metre stick is balanced on a knife edge at its centre. When two coins each of mass 5gm are put on top of the other at 12cm mark, the stick is found to be balanced at 45.0cm. determine A.mass of the metre stick B.reaction of the support at 45cm pivot
question 4 Why did we include the 2m distance with 80N in the anticlockwise moment even they're on the right side of the pivot? I'm not even sure I'll get a response 😢
i wish in the exams it will be as easy as this ahh.. Btw we are doing May/june next year we were supposed to do oct/nov this year but cuz of corona everything got messed up x.x
In reality, maybe, because the beam would have a mass. But in this question we are assuming everything is perfectly balanced and the beam itself has no mass (i know, it’s sometimes silly the assumptions we have to make!)
i absolutely hate this topic
Uh Oh! Hopefully this video helped a bit!
same :|
Same
Haha these are free mahala marks
Yea , that 2nd step hits I feel you bro
The vicious clicking of the calculater!!!
Thank you so much dude it’s literally the night before the exam !!
Hope the exam went well!
How'd the exam go
Same !!!!!! The exam is tomorrow 😭 and if I fail God knows whay will happen to me....
Lmaooo samee
SAME MY EXAM IS TOMRW
Thank you very much...I've been battling with moment calculations for the past two years..😢..thanks for making it seem as easy as pie... you're a good teacher 😊
I’m so happy I finally got a clue on this Thanks SIR I’m so delighted 😀
I tried to understand these concepts for the last 2 weeks in class but failed to understand but after seeing this video I understood it better.
Thanks a lot sir it really helped me🫡🫡
Just exploring some resources to share with my students and really great to find your resource. Hope you're still sharing - I've subscribed in hope!
What do a physic teacher do if you throw a brick at him?
He Duckett
If you can understand this Mr Lovatt you are officially a BIS OG
woodsua haha yes he does Duckett. In lightning speed.
Thanks so much I don't know what I'd have done without this 😅🙏🙏🙏
Tbh even though i dislike the topic,the explanation is better than other physics explanation.good video!

A.mass of the metre stick

Thank you sir, you really helped me especially with question 5
tysm!!!! this made things 10 times easier, you're the best!!!
For the last question...I worked using the other distances from the pivot...not the perpendicular ones n still got the same answer howcome
Your lectures are amazing, understood it better than any highschool teacher🥰🥰🥰
OOMMGG thank you sooo much. i didnt understand this in class. You explained it very good.
I have a question on the third equation, how did you get that 500 sir?
1000-1500=500 then you’d get 2f=500 so you’ll divide and the final answer will be 250N/m
Awwwnn, thanks so much for the simple explanation. ❤
A question why will we multiply 5m with 2m?
Because we multpily the force by the distance from the pivot (the middle of the seesaw) not the distance between the forces
l appreciate,but please how do you get number Two
I have an igcse edexcel physics paper 2 and im flopping everything
Is it a must you write the clockwise moments=anticlockwise moments cause of you don't follow that you still get same answer
question 4
Why did we include the 2m distance with 80N in the anticlockwise moment even they're on the right side of the pivot? I'm not even sure I'll get a response 😢
You are going to consider only the distance to the pivot only not the total distance...I hope you understand my explanation.
i wish in the exams it will be as easy as this ahh.. Btw we are doing May/june next year we were supposed to do oct/nov this year but cuz of corona everything got messed up x.x
How'd it go?
Thank you but the question in the description is blury
The great teachers are always on UA-cam and the trash ones in the classroom. Jesus.
thank you very much this video really helped me a lot
Question 3 - 2F = 500, where did 500 come from? and then 250?
even im confused
2F = (1200+300) - 1000
= 1500-1000
=500.
SO.. 2F = 500
So F = 500/2 = 250.
what program are you using for drawing?
This was my nightmare at varsity, but I'm finding it easy now. If I were to go back I'd go straight A on this topic
Wow, you really helped! Thanks🙂
Thanh you so much I finally got the hang of these questions
bro thank you for the questions
Thanks but question number 3 you didn't explain how you got the final answer
Where did he get f x 2😮
Can anyone explain to me why question 4 is not 3F= 80 X 2 +60 X 4 + 90 X 6 ? 😢
Look on the previous calculations to see how he substitute it into the equation
5:11 the F is not going clockwise it is a anticlockwise moment if you look closely you will see the 80N is going the same direction as F.
for 3:51 why did times the force by 2
Because 2 is the distance between the force F and the pivot. And to find moment we multiply the force and the distance
I spent months struggling with something I can understand in just minutes
This questions are way to simple bruh compared to the ones i'm finna get tomorrow.
Ik right
if you are provided with no pivot point then how do u complete?
I still dont understand how to know which one's the clockwise and anticlockwise moment at the beginning of the question. Is anyone able to explain?
Check the movement of your wall clock (the movement of the minute hand of the clock is the clockwise moment)
thanks alot i hope i pass my exam
Any traumatized 2024 students here?
Present😂
Here 😂😭
😭😭
Cool but I am not able to see examples in the description box
i finally understand this topic... tysm....😀😀✨✨✨✨✨✨
in the last question, shouldnt it be an inequality of 1000 x distance > F x distance?
In reality, maybe, because the beam would have a mass. But in this question we are assuming everything is perfectly balanced and the beam itself has no mass (i know, it’s sometimes silly the assumptions we have to make!)
But sir, why is it 0.3 for qs 5?
Bro thanks so much I did not understood it one bit before
Thank you soo Much !!!!! This helped a ton !
How did you get your 2m
why didnt he divide by 0.6 for the first one tf
This is kinda difficult
Thxxx sir I can’t understand what my teacher is saying but this video is really helpful to me 😭
This was Really Nice ❤️
wait isnt ccw positive and cw negative?
Thank you sir this is a very good video I know, we have very good exams on Friday. 😁
I'm so obliged to you sir!
Why not 8 their
Why have 10 there instead of 5
Thanks pro ❤
tysm man. this rlly helped
Of all my months I physics I can't seem to understand moment
What grade u working at
@LovattPhysics thanks to you my number 1 difficulty the exam has vanished😀
Good explanation
very helpful vid tysm
No worries! Thanks for the comment :)
For question 5 i think the answer must be 16.7N
THANK YOU THANK YOU THANK YOU
oh nah my exam is today im failing this 😭
Thank you very much
Thanks you very much ❤️
thank you very much sir
Helped alot
Unit is NM not N
Who else is here before their test/exam
Thank you❤
The last question I didn't follow the perpendicular distance from the pivot but I got the same answer😂
like: 1000×0.5=F×3
500=3F
F=500÷3
F =167N😂
This really helped me a lot! Thanks @LovattPhysics
Me watching this when exams are on Monday 😅
Goodluck bro !
990 th like les go btw ily u bro
thankyou sir
THANK YOU
THANKS❤
how its if want calculate meter
T/F, Torque divided by the force
acc saved me thank you
Legend
thankss
tysmmmm!!!!!!!!!!!!!!!!!
Luv u
Yh but it's easier
Thank you so much
