Specification 4.6.1.4 · Paper 3, Paper 4
Revise: Mass and WeightMoving the same bag from Earth to the Moon would not change the amount of matter it contains, so its mass would remain 2 kg. Its weight would become smaller because the Moon's gravitational field is weaker.
Specification P2.3g · Physics Paper 1
A region of space in which an object with mass experiences a gravitational force.
Use the value of gravitational field strength given in the question; AQA supplies it in calculations.
When stating that weight is directly proportional to mass, specify that gravitational field strength is constant.
Say that all objects with mass have a gravitational field, not just planets and stars.

We describe this interaction using a gravitational field — a region of space in which an object with mass experiences a gravitational force. Earth produces a field around it, so an object placed in that field is attracted towards Earth.
