Gravity is affected by the:

charge of the objects and whether the charges are the same or opposite.

force applied to the object when moving.

mass of the objects and the distance between two objects.

the size of the objects and the difference in charge.

Gravity is affected by the mass of the objects and the distance between two objects.

Explanation:

Gravity is an attracting force that two or more masses exert on each other. Gravity is one of the four forces of nature. This force is very small at the atomic level compared to the other forces, but is the most common at macroscopic distances: a force acting on each object, in the direction of the center of gravity and proportional to the mass of the object.
