Question

What are two things that increase gravity between objects

Answer 1

The gravitational force between two objects is given by:

$force = \frac{GMm}{ {r}^{2} }$

where M and m are masses of the objects and r is the distance between them.

Thus, the two things which can increase gravity between objects is:

1. Distance between the objects - decrease distance to increase gravity

2. Mass of object - increase mass to increase gravity
