[@schooldays5926]

i absolutely hate this topic

[@lovattphysics6366]

Uh Oh! Hopefully this video helped a bit!

[@rohin4429]

same :|

[@atf4920]

Same

[@donmlondy2688]

Haha these are free mahala marks

[@shakibisdream4439]

Yea , that 2nd step hits I feel you bro

[@callumross9101]

The vicious clicking of the calculater!!!

[@60sbabydoll777]

Thank you so much dude it’s literally the night before the exam !!

[@lovattphysics6366]

Hope the exam went well!

[@sattamalharran3336]

How'd the exam go

[@hotmamajamma9836]

Same !!!!!! The exam is tomorrow 😭 and if I fail God knows whay will happen to me....

[@blueile6096]

Lmaooo samee

[@Aisha-gd6dq]

SAME MY EXAM IS TOMRW

[@woodsua452]

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

[@lovattphysics6366]

woodsua haha yes he does Duckett. In lightning speed.

[@AstroBoy622]

I’m so happy I finally got a clue on this Thanks SIR I’m so delighted 😀

[@user-en9rd3gh1w]

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!

[@justsomeone5660]

tysm!!!! this made things 10 times easier, you're the best!!!

[@_.rarebelle]

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 😊

[@Aisha-gd6dq]

Thanh you so much I finally got the hang of these questions

[@sophyrop6195]

thank you very much this video really helped me a lot

[@simoneyob487]

I'm so obliged to you sir!

[@zenest3907]

OOMMGG thank you sooo much. i didnt understand this in class. You explained it very good.

[@bluelove9768]

l appreciate,but please how do you get number Two

[@janethangandu9863]

Thank you sir, you really helped me especially with question 5

[@nclengoz]

For the last question...I worked using the other distances from the pivot...not the perpendicular ones n still got the same answer howcome

[@jeffobi4709]

if you are provided with no pivot point then how do u complete?

[@aarong9034]

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?

[@girl_of_many_thoughts]

Wow, you really helped! Thanks🙂

[@Kuriomaster]

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)

[@cvpidd_]

Thxxxx

[@UnchxrtedChris]

Is it a must you write the clockwise moments=anticlockwise moments cause of you don't follow that you still get same answer

[@chamika.lakmali]

Thank you soo Much !!!!! This helped a ton !

[@NotMeMaybe]

Tbh even though i dislike the topic,the explanation is better than other physics explanation.good video!

[@schickennuggits1800]

tysm man. this rlly helped

[@qondimokoena7574]

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

[@abigailwoods9188]

Cool but I am not able to see examples in the description box

[@cheesetoastyy6902]

bro thank you for the questions

[@chocolatemilk8469]

Your lectures are amazing, understood it better than any highschool teacher🥰🥰🥰

[@hamzamohammed1943]

Bro thanks so much I did not understood it one bit before

[@araflatif9246]

This was Really Nice ❤️

[@mr_bisso2825]

what program are you using for drawing?

[@user-xl4td1hs5m]

Thank you very much

[@mareanahzulu9871]

Thanks you very much ❤️

[@shanayajhaveri254]

This really helped me a lot! Thanks @LovattPhysics

[@user-xh6ul1gn1i]

How did you get your 2m

[@alisanati]

Thank you sir this is a very good video I know, we have very good exams on Friday. 😁

[@tsoanelomotai3]

I have a question on the third equation, how did you get that 500 sir?

[@yaraassaf851]

1000-1500=500 then you’d get 2f=500 so you’ll divide and the final answer will be 250N/m

[@user-uf3dl2sp6g]

This is kinda difficult

[@samsondikamdima1146]

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

[@_SilverHawk]

Thank you❤

[@kareemmina8830]

in the last question, shouldnt it be an inequality of 1000 x distance > F x distance?

[@lovattphysics6366]

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!)

[@azarioeberenz4790]

Thank you but the question in the description is blury

[@_n1ssy._]

I thought anticlockwise is negative so in 3:19 why is your anticlockwise positive

[@rabiiiii]

I have an igcse edexcel physics paper 2 and im flopping everything

[@EmhamdiIssa-sn5dd]

Thanks pro ❤

[@tokyo7671]

very helpful vid tysm

[@lovattphysics6366]

No worries! Thanks for the comment :)

[@Whiz_euphoria]

A question why will we multiply 5m with 2m?

[@DarkestBlixity]

Because we multpily the force by the distance from the pivot (the middle of the seesaw) not the distance between the forces

[@JuanCarlos-zv2pu]

Good explanation

[@yowaimo-wj2uw]

wait isnt ccw positive and cw negative?

[@user-kj5vs4np9v]

i finally understand this topic... tysm....😀😀✨✨✨✨✨✨

[@kashishfatima2176]

thankyou sir

[@Eyebroooo]

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

[@justsomeone5660]

How'd it go?

[@noonesfavorite911]

THANK YOU

[@ProfessorQuist]

thank you very much sir

[@notshahmeer]

Helped alot

[@ericaaryee3783]

Thanks but question number 3 you didn't explain how you got the final answer

[@SAMURAIFFBACK]

THANKS❤

[@eaintyatiaung5808]

Thxxx sir I can’t understand what my teacher is saying but this video is really helpful to me 😭

[@sheva9848]

thankss

[@bwalyamulombwa]

Why have 10 there instead of 5

[@taehyungishot3215]

for 3:51 why did times the force by 2

[@ruthkalaba4378]

Because 2 is the distance between the force F and the pivot. And to find moment we multiply the force and the distance

[@ArpitaRamachandran]

acc saved me thank you

[@nawabmurtaza]

@LovattPhysics thanks to you my number 1 difficulty the exam has vanished😀

[@user-ty4qb1uq3q]

I spent months struggling with something I can understand in just minutes

[@bliss2681]

why didnt he divide by 0.6 for the first one tf

[@Ogretoe2231]

Question 3 - 2F = 500, where did 500 come from? and then 250?

[@iamshawn0012]

even im confused

[@icantwu]

2F = (1200+300) - 1000
= 1500-1000
=500.
SO.. 2F = 500
So F = 500/2 = 250.

[@tatoman4103]

Legend

[@taehyungishot3215]

tysmmmm!!!!!!!!!!!!!!!!!

[@abachevictor897]

Unit is NM not N

[@salaheldinwahba8291]

990 th like les go btw ily u bro

[@oceanchan5782]

Can anyone explain to me why question 4 is not 3F= 80 X 2 +60 X 4 + 90 X 6 ? 😢

[@GabrielleGayleOfficial]

Look on the previous calculations to see how he substitute it into the equation

[@GabrielleGayleOfficial]

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.

[@indiaxxxz]

oh nah my exam is today im failing this 😭

[@muazfadani9383]

how its if want calculate meter

[@tokyo7671]

T/F, Torque divided by the force

[@kristianandrew2866]

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😂

[@IfedubaIfeoma]

This questions are way to simple bruh compared to the ones i'm finna get tomorrow.

[@skoobydooz]

Ik right

[@Rzs.254]

Who else is here before their test/exam

[@patiencephiri6480]

Me watching this when exams are on Monday 😅

[@GabrielleGayleOfficial]

Goodluck bro !
