An object's weight is defined as the force due to gravity acting on the object. Because the force due to gravity acting on an object changes based upon the location of the object, an object's weight can change with its location. Thus, an object's weight on the moon is not the same as the object's weight on the surface of the earth, even if the object's mass remains constant. However, at or near the earth's surface, an object's weight is fairly constant.
Let's imagine that gravity is the only force acting on a person. The net force acting on that person would then be gravity, and according to Newton's Second Law of Motion, the net force acting on an object is equal to the object's mass multiplied by its acceleration.
What is the acceleration of a person on whom gravity is the only acting force?
