Reference: AQA
Calculated using W = m × g, where m is the mass in kilograms and g is the gravitational field strength in newtons per kilogram.
The gravitational force acting on an object, measured in newtons (N) and directed towards the centre of the attracting body.
A force in newtons that depends on gravitational field strength, unlike mass in kg which stays the same everywhere.
Calculated using W = m × g, where g is gravitational field strength, and distinguished from the applied force.
A force acting downwards due to gravity, which is initially greater than drag so the object accelerates.
A force measured in newtons that depends on gravitational field strength, and is not the same as mass.
