What is the relationship between mass and weight in terms of formula

Answers


Mass is a measure of the amount of matter contained by an object, while weight is a measure of the gravitational pull on an object. As the gravitational force exerted by Earth is the constant upon which mass is calculated, the values of an object's mass and weight on Earth are approximately equal depending on geographic location.
