Detailed explanation-1: -On Earth, the weight of the body (like any other object) is given by Newton’s laws as mass times gravitational acceleration (w = m * g). That is, the weight of an object is determined by the pull of gravity on it.
Detailed explanation-2: -Weight is the vertical force exerted by a mass as a result of gravity. Weight can also be defined as the strength of the gravitational pull on the object; that is, how heavy it is. Weight is dependent on gravity.
Detailed explanation-3: -Gravity is affected by the size of an object and the distance between the objects. When the mass of an object increases the force of gravity increases as well. If an object’s weight is greater than the other object’s weight, then the object with the greater weight will land first.
