I always dreamt of the day where I could unsubscribe to your channel. I know that sounds weird, but chemistry was hell for me and I had to take it all the way to orgo 2. I graduated university last Wednesday. Just wanted to say thank you for all of the helpful videos, I wouldn't have graduated without the help. So happy to be done with this chapter in my life. For everyone in my past position, you can do it! Work hard and the success will follow you.

My teacher taught us to include a scale of maybe 1cm:10N and draw the vectors according to the magnitude and direction. After that he taught us to measure the resultant vector and use the scale to find the force.

Parallel vectors → Parallel angles(opposite angles equal to each other) → (solved: two sides and one angle known) → Law of cosine → Done

If i pass physics class, its all thanks to this guy

[nyanya]

u posted just when i needed this :0 thank you so much!

[BongjohEthel-lq]

Please keep up with the good job. Excellent and entertaining.

[maheletmahelet]

thank u too much u are always helping me its best to get your tutor rather than to have teacher in home spending money for him, is better to spend titrabytes on your tutor. Im very glad of your tutor keep going

[nurasylnurasyl]

in this way children can also understand you😃😃, thankfull

[educationforknowledge]

Best math and physics and chemistry teacher

[favourebubechi]

Thank you bro. This was really helpful

[Ibitoroko-omieTamunoene]

Thank you so much for this video... I finding difficult with my textbook you made me understand everything

[mychemicalreaction]

how do you know which method you have to use and when? The parallelogram method or the triangle method

[primekidus]

But how do we find the direction suing the parallelogram method?
Please respond fast, my test is on monday

I got R=140N, 30 degrees N.E..

I used a scale of 1N=.1cm to fit in a notebook😅😅. 7.3 difference. Very little difference right?😅😅

I do 1000 google searches and then finally come to here . This being the last search.

Isn't the formula is a²+b²+2abcostetha

[sofe]

what if I use displacement instead of force

[imibee]

Why are you breaking F2 and F1 into their respective Fx and Fy component before finding Fr?
Can someone plz help?
