- The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. For an object in free fall, so that gravity is the only force acting on it, then the expression for weight follows from Newton's second law.

Oct 17, 2024 · Weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon. Weight is a consequence of the universal law of gravitation: any two objects, because of their masses, attract each other with a force that is directly proportional.

The broadest definition of weight in this sense is that the weight of an object is the gravitational force on it from the nearest large body, such as Earth, the Moon, or the Sun. This is the most common and useful definition of weight in physics.
The units of force are newtons, the units of mass are kilograms, and therefore the units of the gravitational field must be newtons over kilograms, or people will say it newtons per kilogram. So, let’s review the fundamental features of this gravitational field.
The weight of an object is the gravitational attraction between Earth and the object. The gravitational field is represented as lines that indicate the direction of the gravitational force; the line spacing indicates the strength of the field. Apparent weight differs from actual weight due to the acceleration of the object.
The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.
