Question

What is the difference between mass & weight?

Answer 1

Answer:-

Mass :- mass is defined as the quantity of matter contained in it is known as mass.

• It's SI unit is Kg .

• Mass is a scalar quantity.

• Mass is interconvertible in Energy by Einstein mass - energy relation .

• Mass of a body is constant at any place in universe.

Weight :- It is the force by which earth's attracts any objects towards its centre is known as weight .

• It's SI unit is Newton .

• It is a vector quantity .

• It can be vary with acceleration due to gravity .

• Weight can be changed in different places in universe .

• Weight is mathematically product of mass and gravity .

Weight of a body is given by formula:-

$W = m.g$

Answer 2

                        Difference Between Mass And Weight

MASS:

• It is the amount of matter present in an object.
• The mass of a body is constant around the universe.
• SI unit of mass is Kilogram/Kg.
• Mass can never be equal to 0.
• Mass is scalar quantity.

WEIGHT:

• It is a force with which an object is pulled toward the Earth.
• Weight varies from place to place as the acceleration due to gravity varies.
• SI unit of weight is Newton/N.
• Weight can be equal to zero.
• Weight is a vector quantity.
