density of plastic

What is Density of plastic:

The density of a substances is generally known as mass per unit volume. And The SI unit is Kg/m3.

Mass Versus Weight:

Always there is confusion in people between mass and weight. Actually the mass of an object is referred to its weight. In the scientific concepts mass refers loosely to the amount of matter in an object. Whereas weight refers to the force exerted on an object by gravity. In the other words, an object with a mass of 1.0 kilogram with weigh approximately 9.81 newtons on the surface of the earth. (Its multiplied by the gravitational field strength), Where the object weigh will be less at Mars because there gravity is weaker, more on Saturn and negligible in space.

As of conclusion Mass is constant at anywhere in earth but weight is varied due to gravity.
