In the pheesical sciences, the wecht o an object is the magnitude, W, o the poust that maun be applee'd tae an object for tae support it (i.e. hauden it at rest) in a gravitational field. The wecht o an object equals the magnitude o the gravitational poust actin on the object, less the eftercome o its buoyancy in ony fluid in whilk it micht be doukit in.[1] Naur the surface o the Yird, the acceleration due tae gravity is aboot constant; this means that an object's wecht naurhaund tae the surface o the Yird is rochly proportional tae its mass.
