Answer 2

$\underline{\huge\mathfrak{Answer:}}$

The SI unit of Mass is kilogram (kg).

The SI unit of weight is newton (N).

$\underline{\textbf{Mass:}}$

The mass of a body is the quantity of matter ( or material ) contained in it . Mass is a scalar quantity because it has only magnitude but no direction . $\textbf{The SI unit of mass is kilogram}$ , which is written as kg . A body contains the same quantity of matter wherever it is . In any part of the universe , the mass of an object is the same . The mass of a body is constant and doesnot change from place to place . Mass is also called the measure of the inertia of thr body , and is called inertial mass . The mass of a body cannot be zero .

$\underline{\textbf{Weight:}}$

The weight of a body is the force with which it is attracted towards the centre of the earth . Simply , the force of gravity acting on a body is called its weight . Weight is a vector quantity . $\textbf{Its SI unit is newton}$ . Weight is not a constant value , as it changes from place to place . The weight of a bidy can be zero .
