Question

give difference between scalar and vector quantity?

Answer 1

scalar: a physical quantity which have only magnitude but no direction.
eg: speed,mass,distance
vector: a physical quantity which have both magnitude and directon.
eg: displacement, velocity

Answer 2

Those Physical Quantities which are described by specifying only their numerical values i.e., magnitude, are called Scalar Quantities. Examples Are -> Distance,Speed,Mass,etc .
Those Physical Quantities which are described by magnitude as well as direction are called vector quantities.
Examples are -> Displacement,Velocity, Acceleration, Force,etc. Answer..
