Gravity is the force that attracts two masses together. Weight on Earth is the force of gravity acting upon an object on Earth. The formula for force is: F=ma -or- Force=mass x acceleration So, multiplying an object's mass by its acceleration due to gravity (9.8m/s2 on Earth) will give you the measurement of the force of gravity acting upon the object, also known as the object's weight.
mass of object *force of gravity
Weight is essentially the force (equal on both) of gravitational attraction between two objects, and depends on the total mass (of both objects) and (the square of) the distance between them.
When the only force on an object is the force of gravity,we say that the object is in "free fall".
The force of gravity on an object is called its weight.Note that mass is what CAUSES this force of gravity.
Mass
because the earth has mass. Gravity is a the force of attraction that is related to the mass of an object. The greater the mass, the stronger the force of gravity.
The force of gravity must be greater than the mass of the object

Normal force is the force of a surface acting on an object( the normal force is perpendicular to the plane of contact). This force is directly related to the force of gravity, as the third law of newton state that when a force is applied to an object it will react with an equal force in the opposite direction. So when an object is placed on a surface, the force of gravity is acting on it (pulling it down), but the is object remain in place due to the normal force (which is pulling up on the object). In addition, a change to the force of gravity will result in the same change to the force of normal, to allow an object to remain stationary.
weight, The weight of an object is the force of gravity acting on it.
The upward force would have to overcome gravity, so the force should be F > -mg. Since the upward force and gravity work in opposite direction you can disregard the mass of the object (they cancel: F(gravity) = F(upward) => mg = -m(g+x)) . Consequently the object's mass is irrelevant.
