Detailed explanation-1: -The gravitation force between the earth and object is called weight. It is also equal to the product of acceleration due to gravity and mass of the object. Weight=m×g, where, m= mass of the object, g= acceleration due to gravity =9.
Detailed explanation-2: -Mass is a measure of the amount of matter in an object; weight is the measure of the gravitational force exerted on an object. The force of gravity on a person or object at the surface of a planet is known as weight.
Detailed explanation-3: -The force exerted on a body by gravity is called weight. The force on a body is dependent on the mass, m, and the gravitational acceleration, g, of an object near the Earth’s surface. The force, F, of the body equals the product of the mass and the acceleration, i.e.: F=mg. This is consistent with Newton’s second law.
