A) mass, in physics, the quantity of matter in a body regardless of its volume or of any forces acting on it. The term should not be confused with weight, which is the measure of the force of gravity (see gravitation) acting on a body.

B)Mass is a scalar quantity

C)The SI unit of mass is kilogram

D)Wherever the object is placed, its mass remains constant. Thus, when the body is taken into any deep space, its mass never changes. The weight of the body might change with the change of place.
