Q:

What increases the force of gravity between two objects?

A:

Quick Answer

The force of gravity between two objects can be increased by reducing the distance between them. The force of gravity is influenced by the masses of the two objects and the gap between them. Gravitational force generally increases as objects become more massive and draw closer together.

Matter is defined by its volume the rest mass it possesses. Gravity is a universal phenomena where all matter is attracted towards all other matter. The Earth also exerts a gravitational pull on all terrestrial objects that prevents them from drifting upwards. It is towards the center of the planet where the force is directed.

The gravitational force between two bodies is directly proportional to the masses and inversely correlated to the square of the distance. The relationships between gravitational force, mass and distance can be mathematically expressed using the equation Fg = G (m1m2/r2), where "Fg" denotes the gravitation force, "m1" and "m2" indicate the masses, "r" represents the distance and "G" is the universal gravitational constant. This formula is also known as the law of universal gravitation.

Based on the equation, the distance r is multiplied by itself, which means that the gravitational force decreases by a factor of four when the gap is doubled. Conversely, when the distance is reduced by half, the gravitational force increases by a factor of four.
