Mass- it is the amount of matter contained in body. - its SI unit is kilogram . - is constant for all places. - it is scalar quantity. - it is measured using a pan. balance. ________________________Weight - it is the product of mass and g. -its Si unit is newton. -it differs from place to place. -it is vector quantity. -it is measured using spring balance

Mass
Weight
1
Definition
Mass is simply the measure of the amount of matter in a body.
Weight is the measure of the amount of force acting on a mass due to acceleration due to gravity.
2
Denotation
Mass is denoted by “M”.
Weight is denoted by “W”.
3
Formula
Mass is always constant for a body and there are several formulas to calculate mass.
One way to calculate mass is:
Mass = volume × density
Weight is the measure of the gravitational force acting on a body.
Weight can be calculated from the following formula:
Weight = mass × acceleration due to gravity
4
Quantity Type
Mass is a base quantity.
Mass only has magnitude and so, it a scalar quantity.
Weight is a derived quantity.
Weight has both magnitude and direction (towards the center of gravity) and so, it is a vector quantity.
5
Unit of Measurement
The SI unit of mass is Kilogram (Kg).
The SI unit of weight is Newton (N).
6
Gravitational Effect
Mass does not depend upon gravity and is constant everywhere.
Mass can never be zero.
Weight is dependent on the gravity and so, it varies from place to place.
Weight can be zero where there is no gravity (like space).
7
Measuring Instrument
Mass can be easily measured using any ordinary balance like beam balance, lever balance, pan balance, etc.
Weight can be measured by a spring balance or by using its formula.
