Specification 6.5.1.3, 6.5.4.1.5 · Paper 6
Revise: GravityEarth has a gravitational field around it: an object with mass placed in this field experiences a force of attraction towards Earth. This force is the object's weight. Near Earth's surface, weight acts vertically downwards, towards Earth's centre.
The force acting on an object due to gravity.
Paper 5, Paper 6
The gravitational force acting on an object. Weight is a vector measured in newtons (N), directed towards the attracting body.
Revise: Vectors and scalarsWeight is the gravitational force acting on an object. It has a size and acts towards the attracting body—for an object near Earth's surface, towards Earth's centre. Weight is therefore a vector, measured in newtons rather than kilograms.
The force acting on an object due to gravitational attraction, measured in newtons (N).
Distinguish mass in kilograms from weight in newtons: weight is a force.
Draw a weight arrow vertically downwards from the object's centre of mass.
Name the downward force as weight and the upward force in air as air resistance, not air pressure.
