[@lavenderflowerl]

3:21 - Start of Seesaws Moments
3:24 *the pivot is the Middle* 3:26 *apply the first force on the seesaw*
3:30 *the perpendicular distance, which is between the pivot and the force, is for the first force on the seesaw*
3:40 *the Moment/the working out for the first Force*
3:47 *anticlockwise and clockwise*
NOTE:
it is defined *anticlockwise* and *clockwise*
rather not define UP and DOWN on the Pivot Seesaw
3:57 *first force is an Clockwise moment*
4:04 *apply the second force on the seesaw*
4:07 *second force is also an Anticlockwise moment*
4:11 *explaining the overall working out of the Seesaw for the Moment answer*
4:21 *what happens when the seesaw is balanced*
4:37 (what im left on and doing more notes later)

[@sheilabirling]

i’ve never understood moments until now! thank you so much, these videos are a godsend 🙏

[@memosaleh2585]

At 3:49 I think 600 should be written as N not M. Correct me if im wrong? But overall your videos are so helpful thank you!!

hi at 3:45 i think. u put at 600m instead of 600n? or im just confused pls reply!!!

yes, its definitely a mistake. i also think another mistake was 2m and not 200cm

if someone said that use use long spanner over short spanner because long spaner of great moment of force is he/ she correct ?

Do you have a chemistry video about naming compounds??

[@Cognitoedu]

Hi Kuba I’m sorry to say we don’t at the moment 🤦‍♂️

[@kubahabet6155]

@@Cognitoedu ohh... I really need to revise on naming compounds cause I don't really understand it but you are the only one that can explain science the best so I thought that maybe you have a video explaining how to name compounds but you dont. So I tried other science channels to see if they had a good video about naming compounds but I still didn't understand it. So i'll just wait until you make a video about naming compounds.

@@kubahabet6155 a bit late but have you checked out FuseSchool and freesciencelessons? apart from cognito, these channels help me out quite a lot with science doubts.

How do you know which side will be clockwise and which will be anti-clockwise?

[@honeydew1411]

why did we change 20 cm to to .2m? is it because distance is measured with m?

[@masterwars3443]

Yes

[@sc6pe300]

3:56 is it supposed to be 2m x 600N instead of 2m x 600m? Correct me if im wrong

Hi,your videos are really useful, can you please explain what's pivot?
Fun fact=I show my teachers your videos and tell them to explain like this :')

[@JatPhenshllem]

Pivot - the turning point.
How do your teachers respond?

[@materialgirly]

So helpful!

[@Nkematiah-li7xe]

THANKS🙏🏻

[@mannanhanda5564]

Hello, I have 2 questions
1) I noticed that the formula for calculating moment is the same as the formula of work done (Force * Distance). So does that mean that if we have a question the work done = moment?
2) In the video the formula for calculating moment is given as M = F d. Is the symbol for distance s or d?

[@purgeziadk1009]

Answer one: no for levers it's moment= force × distance for work it's work= force × displacement
Answer 2: no speed is S distance is D
