Reference: AQA
A force measured in newtons that depends on gravitational field strength, unlike inertial mass, which is a property of the object.
Equals mass times gravitational field strength, W = m g, measured in newtons, with mass in kilograms and g in N/kg.
A force in newtons, calculated as W = m × g, which changes with location while mass stays the same.
A force calculated using W = m × g, where g is about 9.8 N/kg on Earth.
The force of gravity acting on an object, measured in newtons.
The force acting on an object due to gravity.
