The force of gravity on a mass, calculated as W = mg, where m is mass in kg and g is gravitational acceleration in m s⁻².
The gravitational force on a mass, given by W = mg, where m is mass in kg and g is gravitational acceleration in m s⁻².
The gravitational force exerted on a mass m by a gravitational field g, also measured in newtons.
The downward gravitational force acting on a particle of mass m, given by W = mg.
