what are the two types of physical quantities
Answers
Constant or ratio
Such quantities have the only magnitude, for example, refractive index, dielectric constant and specific gravity. Such quantities have no units.
Scalars
These quantities have magnitude and unit. Some of them may have direction also but vector laws are not applied. Examples are the charge, mass, distance, speed, and current.
Vectors
These quantities possess magnitude, unit, and direction. They also follow the triangle law of addition. For example velocity, force, momentum, torque, and displacement.
Phasors
These possess magnitude (amplitude) and phase. Try follows triangle law. Simple harmonic motion (SHM), waves. AC voltage and AC current are phasors.
Answer:
We have two types of physical quantities: fundamental and derived.
FUNDAMENTAL - These quantities are the basic ones. They tell something about how they are measured. ...
DERIVED - The term alone speaks for itself. These quantities are the combinations of the fundamental quantities
