Weight

Weight is the force in which the earth attracts an object.

W=mg

W is the weight of the object, in newtons (N)
m is the mass of the object, in kilograms (kg)
g is the acceleration due to gravity, in metres per second (ms^-2, see acceleration).

A greater force is needed in order to attract an object with more mass.

This means that objects with more mass will have more weight, in the same gravitational field.

Question	Answer
Weight	W=mg, where W is weight in N, m is mass in kg, and g is acceleration due to gravity in ms^{-2}.
How do mass and weight relate in the same gravitational field?	Objects with more mass will have more weight because a greater force is needed to attract more mass.
