Question

What is vector and characteristic of good vector?

Answer 1

Vector quantities have 2 characteristics,a magnitude and a direction.vector quantities of same type you have to compare both the magnitude and direction.

Answer 2

All the physical quantities that have both tha magnitude and direction and follows the vector law are known to be vectors.

Extra Information:-

Polar vectors:- These are the vectors that have a starting point as a displacement, force etc.

2. Axial vectors:- These vectors act along the axis of rotation and gives a rotational effect. It follows the right hand screw rule for angular velocity, angular momentum, etc.
