Scalar and Vector Quantities
- Scalar Quantities: The physical quantities which are specified with the magnitude or size alone are referred to as Scalar Quantities. It is one – dimensional measurement of quantity like mass or temperature. A physical quantity which has force but no direction. For example, length, speed, work, mass, density, etc.
- Vector Quantities: Vector Quantities refers to those physical quantities which are characterized by the presence of both magnitudes as well as direction. It is indeed a quantity that requires both of magnitude and direction in order to identify the right quantity. For example, displacement, force, torque, momentum, acceleration, velocity, etc.
