That is a great question and a little tricky. I believe you'd still call it a vector quantity. The reason is that it isn't true that it "only represents directions". How do you define an angle? You have an XY plane and you draw a ray somewhere from the origin to a point P(x,y). The angle is defined between the x-axis and the ray that you defined. That RAY is a vector. You have to draw an arrow which represents length then measure an angle. Ask yourself, how do you define or measure an angle without having at least one ray on a sheet of paper. You can't. The angle number means nothing without the accompanying ray. So, basically that ray represents a vector - it has length and direction (angle). Hope this helps!

@@MathAndScience year , I think you are getting really close 😆😐😄

@@MathAndScience also i don't think scalars don't have direction, they are just not described by their directions because they are multi-directed like distance, while a uni-directional quantity like displacement is vector

@@amjadhussain3584 I hear what you’re saying, but scaler’s really do not have any direction at all. The best example of a scale or quantity is temperature. At every point in a room there is a number, called the temperature, that expresses the value of the temperature at that point. But temperature has no direction it is just simply a number at every point in space. That is a scaler quantity.

Thank you!

Thank you so very much!!

Yes exactly. You can visit mathandscience.com to learn more. Thank you!

Keep it up

oh funny u

How

vector

Hope you passed?

@@AdyI.R Yessss That was a y10months ago..now i no longer offer the course💜

Awww I wish!
