The gravitational force acting on an object, measured in newtons (N).

Specification 4.5.1.3 · Paper 2
The force acting on an object due to gravity, measured in newtons (N).
Revise: GravityAn object's weight is the force acting on it due to gravity. Because weight is a force, it is measured in newtons (N) and has a direction. Near the Earth's surface, that direction is towards the centre of the Earth.
The force on a mass due to gravity, measured in newtons.
Specification 2.4, 2.16, 2.17, 2.18, 7.1P, 9.4, 15.17P · Paper 1, Paper 2
The force on an object caused by a gravitational field; it is a vector.
Revise: Recalling Vector and Scalar QuantitiesWeight is the gravitational force acting on an object. Every force has a direction, so weight is a vector and is measured in newtons. Near Earth's surface, an object's weight acts towards the centre of Earth.
The gravitational force acting on an object because it has mass; it is measured in newtons (N).
The force acting on a body because it is in a gravitational field, measured in newtons (N).
The gravitational force acting on an object, directed towards the centre of the Earth.
The downward force on an object caused by gravity; it is equal to mass multiplied by gravitational field strength.

The gravitational force acting on an object.
Revise: Forces as vectorsThe arrow should also be labelled to identify the force, such as weight, friction or normal contact force.
The force produced by gravity on an object; near Earth it acts vertically downwards.
The gravitational force acting on an object, directed vertically downwards.
The force acting on an object because it is in a gravitational field, measured in newtons (N).
The force exerted on an object by gravity, measured in newtons (N).
The weight of an object: the force on it due to gravity, measured in newtons (N).
Paper 1, Paper 2
The force acting on an object because of gravitational attraction, measured in newtons (N).
Revise: ForcesThe third-law partner of the table’s upward force on the object is the object’s downward force on the table. It is not the object’s weight. Weight and normal contact force can be equal and opposite when an object rests on a table, but both act on the same object and are different types of force, so they are not an interaction pair.
The force exerted on an object by gravity. Near Earth’s surface, weight is mass multiplied by gravitational field strength.
Do not give weight in kilograms: weight is a force measured in newtons (N), while mass is measured in kilograms (kg).
A directly proportional relationship must produce a straight-line graph through the origin. This applies to weight against mass only while is constant.
On a force diagram, draw the weight arrow from the object's centre of mass and towards the centre of the Earth.
