Very informative! I hope more interesting videos to come! 😊

Thank you so much sir! I think for the last problem on this video. We weren't able to cover the direction and the angle? Just wanted to double check that we can just use sin or cosine, raised to the power of negative 1 to find out the degree of the angle? I got 63.43 degrees, so would the full answer would be 2.2km, 63.43 degrees N of E? If not, could you please let us know the answer to the direction part of the right angle problem? Thank you!!!

Sir, do you also cover polygon method?

[@USTPhysicsLectures]

the head-to-tail method is actually the polygon method.

Hi po sir, your videos have been very helpful for my physics , and I’m very grateful for this. Tiny question sir, is the parallelogram method applicable for 3 or more given vectors? How will we do it, if it is applicable po? Our prof is asking us to draw a parallelogram method with a problem of 3 vectors, but then...i think it looks erroneous. Thank u sir so much.. God bless

[@USTPhysicsLectures]

sorry for the late reply. You can apply parallelogram even with 3 or more vectors. what you do is to add first the two vectors say (A+B) and the result of A and B say Q will be added to the third vector C, i.e. (Q+C)

How about po if the three vectors are not the same direction? For example 15N 30° N of E, 25N west, and 45N 25° S of W?
