what is weight?
Weight is the force that acts on a body, from its centre of gravity.

how is weight calculated
The acceleration due to gravity at any point on earth is 9.8 m/s^2

What is gravitational field stregth
the force exerted on a unit mass of a body at any location in the gravitational field. It is taken to be 10N/kg

how to calculate weight
Calculating the weight of a body is frequently asked for the exams. The value of the gravitational field strength(mostly given, if not take as 10) is multiplied by the body's mass to give its weight

does mass vary from place to place
The mass of a body is the amount of matter a body contains, and according to Einstein a body's mass is not lost unless an external force is applied to remove the mass.

does weight vary from place to place
the weight of a body is given by the mass multiplied by the gravitational field strength. Although the mass may be the same, the gravitational field of an area ca change eg: g= 1.6 on moon and 9.8 on earth
