I can't find the video that explains in detail why you use sin for x and cos for y on an incline plane problem. Can you please send me the link or post it?
I don't understand why you switched sin (as x) and cos (as y) here and I referred back to the trig video but it only talks about sin being y and cos being x, could you elaborate?
syn and cosx are shortcuts for standard setups. However you can't forget that SOCAHTOA still applies. When the angle is not standard (0 degrees right horizon) then you have to take the new setup into account. That being said, which point in the video is giving you trouble?
Leah4sciMCAT @5.:20 you have equated both equal as they are acting in opposite direction. But as per newtons third law they should be equal and opposite i.e. Fn = -Fg. This is confusing. Sometimes I see as both forces equal to each other in equations and sometimes as equal but opposite that is with a negative sign. When to use which format?
very helpful and super easy to understand! love the hammock example
Lyudmyla Shymkiv Thank you :)
Hammock's used to throw me before I learned how to simplify the free body diagram
This is very good. Thank you so much
You're very welcome!
Fantastic ! It works, I like it!
Glad it helped :)

See links in the video description. For more help with this, I recommend joining the MCAT study hall: join.mcatstudyhall.com/
excellent.
Thanks!

Fantastic video to understand basic concepts to help with more complex problems! Thankies!! ='-'=
Mai Smith Thank you :)
If the forces are opposite then why aren’t we doing Ff= -Fw?
At which point in the video?
I would say there is a negative INSIDE the Fw. For example, Fw = - 2 N
