In the physical sciences, the weight of an object is the magnitude, W, of the force that must be applied to an object in order to support it (i.e. hold it at rest) in a gravitational field. The weight of an object equals the magnitude of the gravitational force acting on the object, less the effect of its buoyancy in any fluid in which it might be immersed. Near the surface of the Earth, the acceleration due to gravity is approximately constant; this means that an object's weight near the surface of the Earth is roughly proportional to its mass.
