Can we have physical quantities having magnitude and direction but they are not vectors?
Yes
No
Quantities like current and time have magnitude and direction but do not follow the triangle law of vector addition.
Can you add two vectors representing physical quantities having different dimensions? Can you multiply two vectors representing physical quantities having different dimensions?
A physical quantity having magnitude and direction is know as vector.it means pressure,surface tension are also vectors . but these are not vectors .WHY.
Are all physical quantities that have magnitude and direction vectors ? Give example to support your answer . When is a physical quantity called vector ?
Current and time have both magnitude and direction but yet they are not considered as vectors. Why??
