Finding a resultant vector

An explanation of the difference between vectors and scalars, and a demonstration of how to calculate the resultant of two vectors.

Thank you Cowen Physics!! Very cool!!1!

[joshuastine]

my problem was just like you described river current velocity and boat velocity what a coincidence

[akhz]

thank you so much i have an exam tomorrow and i didn’t understand this lesson

[PossessedRosary]

See, this is very amazing and helped me a lot, but for some reason I cannot understand how you came with 54.5? Could you explain to me please?

[elijahjane]

can you explain this and answer pls.. i don't really understand. "what is the resultant of vector A.a 30N force pulling a body east and vectorB, a 10 N force pulling the same body south using the parallelogram method? given:find r and scale: 1 cm =5N.... i already solve the r which is 31.6 ..just i don't know how to graph them

[kangsanchoi]

a Tangeant ( or tan-1) x (7 divided by 5) becomes 54.5 and this is correct

[archelllecera]

Which is the resultant vector of that, is that the length of hypotenuse or the tangent teta?

[RandomYoutubeShorts]

Displacement is a scalar
The shortest possible lenght between two points

[olivacourtneylove]

After that 54.5? That's the direction right? You'll add that 54.50 to 8.60 m/s to get the resultant vector?

[NITINNITIN-buwk]

Sir, can you explain how did u got the angle 54.5 .

[lllos]

what if it has m/s2 does that make any difference how to solve it

[Mattpewr]

Will i turn the hypotenuse into a decimal if i cannot find a square root like square root of 53?

[samidalao]

aren't you supposed to use arctan?

[kervinjetro]

how did he get the answer 8.60 ms-1???

[MdIshran..]

You are wrong the main difference between vector and scalar is vector follows vector law of addition and scalars follow algebraic addition. Scalars may or may not have direction like current have direction but it is a scalar quantity

COMMENT IN WHICH CLASS OR Year you are 😃

Thodi hindi bhi bol liya karo master ji

well i liked this vid until he brought out the trigonometry
