Answer 2

Hello friend!


1. Scaler quantity : A physical quantity that has only magnitude is called a scaler quantity or simply, a scaler. A scaler quantity is thus completely specified by its magnitude - a number and unit, if any.
Examples: Mass, length, time, temperature, speed, energy, pressure, electric current, refractive index, etc.



2. Vector quantity: A physical quantity that has a magnitude as well as a direction acossiated with it, and combines according to the laws of vector addition, is called a vector quantity or simply, a vector.
Examples: Force, displacement, velocity, acceleration, electric field intensity, magnetic induction, etc.
