Detailed explanation-1: -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.
Detailed explanation-2: -The weight of a body is the product of mass and acceleration due to gravity on earth. The mass of a body remains constant but acceleration due to gravity is inversely proportional to the radius of earth.
Detailed explanation-3: -Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
Detailed explanation-4: -Gravitational force is responsible for the weight of physical objects. The weight is a force which is measured in newton(N). It is the force acting on an object due to gravitational pull.
Detailed explanation-5: -It points straight downward towards the center of the earth. The force of gravity acting on an object is called its weight.
