This channel is so underrated! this is so easy to understand I understood this in like under 5 minutes than my teacher explained it to me for 2 classes. This was so simple and convenient...Thanks Congito!!

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)

Brother, I wanna highly appreciate you for teaching me a difficult topic made so much more easier man, my class is really noisy and no one listens to my teacher so I usually can’t hear my teacher and understand but you made it lot easier in a 5 minute video Thanks Man I highly appreciate it

[@turtleboy3288]

Lucky... My teacher IS the problem, he's so unbothered and sounds so sleepy all the time, everyone i know in my class *hates* him, they tell me that they can't understand ANYTHING... so, until i found this and his other videos, I might not screw up in the test.

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

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.

[@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 Your welcome

[@jacobmwaseba9142]

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

Because the si unit of distance is m

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