Final answer:
As the mass of a body increases, the gravitational force between the Earth and the body increases as well. This results from gravity being a property of mass that causes any two masses to attract each other with a force that is directly proportional to their masses.
Step-by-step explanation:
When the mass of a body increases, its gravitational force of attraction to the Earth also increases. This is because gravity is an inherent property of mass, as stated by Newton's law of universal gravitation: every mass attracts every other mass with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Therefore, as the mass of an object increases, the force of gravitational attraction between the Earth and the object increases accordingly.
For example, if you were to add mass to an object on Earth, the gravitational force it experiences due to Earth's gravity would increase. This is because the Earth, with its large mass, dominates the gravitational interactions experienced by objects on or near its surface. Even as we move away from Earth and the acceleration due to gravity changes, the expression for gravitational potential energy confirms that the increased mass leads to a stronger gravitational pull.
In the context of astronomical bodies, such as planets, as their mass increases, their gravity increases, which can lead to compression and a decrease in size for very massive planets. This illustrates the relationship between mass, gravity, and the material properties of celestial objects.
