Which of the following makes gravity increase?

a. the mass of forming objects increases.

b. the mass of forming objects decreases.

c. the spherical shape of planets provides the momentum needed to increase gravity.

d. the mass of forming objects is constantly the same.

The answer is A. The mass of forming objects increases.

Gravity between objects depend on two things: distance and mass. The farther objects are apart, the lower the gravity. However, the mass of an object is directly proportional to gravity. As mass increases in an object, the gravity increases as well.
