- The weight of an object is the force on it due to the gravitational pull of gravity at that point. Since it is a force, weight is measured in Newtons (not kilograms). The force of gravity is different on different planets, so the weight of an object on different planets (or moons) is different from its weight on Earth.

Mar 4, 2015 · Weight is a quantity that you measure for a particular object, while gravity is a measure of how curved is the spacetime where that object is living. To understand better this difference, think about a light beam traveling along the space.

Weightis the force generated by the gravitational attraction of the earth on the airplane. We are more familiar with weight than with the other forces acting on an airplane, because each of us have our own weight which we can measure every morning on the bathroom scale. We know when one thing is heavy and when another thing is light. But weight, th...
The nature of the gravitational force has been studied by scientists for many years and is still being investigated by theoretical physicists. For an object the size of an airplane, the descriptions given three hundred years ago by Sir Isaac Newton work quite well. Newton developed his theory of gravitation when he was only 23 years old and publish...
Weight is a force, and a force is a vector quantity having both a magnitude and a direction associated with it. For an airplane, weight is always directed towards the center of the earth. The magnitude of this force depends on the mass of all of the parts of the airplane itself, plus the amount of fuel, plus any payload on board (people, baggage, f...
Flying involves two major problems; overcoming the weight of an object by some opposing force, and controlling the object in flight. Both of these problems are related to the object’s weight and the location of the center of gravity. The dream remains that, if we could really understand gravity, we could create anti-gravity devices which would revo...

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.

Jul 27, 2022 · Weight is the force generated by the gravitational attraction of the earth on any object. Weight is fundamentally different from the aerodynamic forces, lift and drag. Aerodynamic forces are mechanical forces and the object has to be in physical contact with the air which generates the force.
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.
The force of gravity, or gravitational force, pulls objects with mass toward each other. We often think about the force of gravity from Earth. This force is what keeps your body on the ground. But any object with mass exerts a gravitational force on all other objects with mass.
