Final answer:
The force of gravity on a 1-kg mass can never be more than on a 2-kg mass because the force of gravity is directly proportional to the mass of an object.
Step-by-step explanation:
The force of gravity on a mass depends on the mass of the object and the distance between the objects. According to Newton's law of universal gravitation, the force of gravity between two objects can be calculated using the formula F = (G * m1 * m2) / r^2, where F is the force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers of mass.
If we compare a 1-kg mass to a 2-kg mass, the force of gravity on the 2-kg mass will always be greater. This is because the force of gravity is directly proportional to the mass of an object. The greater the mass, the greater the force of gravity.
Therefore, the force of gravity on a 1-kg mass can never be more than on a 2-kg mass.
