Sometimes there is confusion and misunderstanding in measuring the Weight and Mass. The Mass and Weight are described as follows.
Weight (W): Weight is the amount of pull exerted on the body by the earth. The weight of a body varies as the distance varies from the centre of earth; therefore the weight of the body varies with its position on earth’s surface. The Weight is generally measured in Newtons (N). The weight is measured with spring balance.
Mass (m): It is the amount of matter contained in a body. The mass of a body does not vary with its position on earth. It remains the same on all the positions on earth’s surface. The unit of mass is kilogram (kg). The mass is measured with lever balance.
Relation between Weight and mass: The relation between the Weight (W) and mass (m) of a body is
W = m.g
Where ‘g’ is acceleration due to gravity.
