Answer 2

Answer:

Scalar Quantities: The physical quantities which are specified with the magnitude or size alone are scalar quantities. For example,  length, speed, work, mass, density, etc.

Vector Quantities: Vector quantities refer to the physical quantities characterized by the presence of both magnitude as well as direction. For example, displacement, force, torque, momentum, acceleration, velocity, etc.
