@cindytg87 Ah I see, silly me I wasn’t thinking about the equation to the Pythagorean Theorem. Thanks for clearing that up cindy ^_^
@XxMorguedxX at 24:00 it’s the Pythagorean theorem and it’s a 3 4 5 triangle
300^2 + 400^2 == 500^2
at 27:20 he enplanes he finding the net force for 2 people pushing on the box. Given the force of one person and the total force applied(net force). the complication comes when he doesn’t specify direction. but it becomes clear that he’s defining a triangle with 2 force vectors. so it turns into the Fnet^2+F1^2=F2^2 problem. F2= Sqrt(12^2+5^2) = 13
Great video, though I had a few questions. In your example at 24:00 you put the vector displacement at 500. I don’t understand how you got that. The same goes for your example at 25:42, how did you get 13 Nt, when you add 12 Nt and 5 Nt? I think I must have missed something here
lol i am like in grade 9 and don’t really get this!
@ 50.35 there is a small mistake:
if u rotate the prime axis about the y-axis
Az’ = Az cosθ + Ax sinθ
Ax = -Ax cosθ + Az cosθ
whereas u have written :
Az’ = Az cosθ + Ay sinθ
Ax = -Ax cosθ + Ay cosθ
please check !
He got a part of this wrong. The actual law is “For each action there is an equal and opposite reaction.” not “For each action there is a reaction.” The reaction has to be quantified in order for this law to stand.

@Chrisspy704 whoah… dont get carried away…
@Kickin321 I have adhd and I find it difficult to listen to one thing and write another so I appreciate the breathing room. Mind you this is on youtube and I can pause, so I see your argument.
The intro song reminds me of ” Resident evil CV save room theme”
so many memories. so nice.
Wow, any 14 year old can go through this and learn something new:D. Better than porn
!!!
good one
ths vedio is very very helpful…………thank u
It was a little repetitive but it was helpful
Nice very basics got it down now.
excellent work!
might just pass my exam now
What a great presentation.
i hate it when people write out (slowly) everything they say.
thanks for this video
very refreshing nice one guys
great lecture
Great lecture sereies to brush up basics!!!
Thanks you so much!!!
thanks u r a g for reall
Thanks for uploading this video.
