Sure! In short, the side that is adjacent to the angle is always cos and the side that is opposite of the angle is always sin. USUALLY cos goes with x and sin goes with y but the second problem is one where that is not the case. Hope this helps!
This video is for my AP Physics students and g=10 for problems on AP tests. It's a simplification that makes solving most problems a lot faster and your answer is generally very close to what you would get with 9.8 or 9.81. Hope this helps!
No way he said zoro like one piece at 3:26 lmao
Can i ask why the cos and sin had flipped such as how cos is usually the x value and the sin is y, but in the 2nd problem you had flipped them?

What are formula for tension when two angles and weight were given
Great video!
must be nice being able to make up an angle, I'm trying to figure out how to do this without the angle. Not a lot of help.
dude same😂💀
so did you ever figure it out? (i need help too)
I've blocked ts out of my mind, I finished all of college physics lol
6:55 how is 30 degree coming?
Where did a 100 come from?
Cause I was taught that you have to multiply 10kg x Gravity.
So 10kg x 9.8 = 98N
These videos are made with the AP Physics test in mind. That test allows students to use g=10 m/s^2 so they can solve problems a bit faster.
@@HowToPhysics omg thanks for the clarification I was using 9.8 and I was stressing over my answer hahah
You said T1 is equal to T2cosθ, but what if T1 has a given angle? How do we solve that
divide t1 by cos theta ig so
in the second problem, what if we solved mg to its components and made mgsin(theta) equal to ma? and then solved for theta?
Isn't 10kg to N: 98.067
Yes but these videos assume you are using 10 m/s/s for g. This is common for test like the AP Physics test.
@@HowToPhysics oh 👍🏻
god bless. this video is so helpful.
Thanks!
You are absolutely amazing, love the content!
Since when is g=10
