So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled.

Impulse is equal to the change in momentum. The correct option is B.

No, never. Is it correct to say that, if no net impulse is exerted on a system, then no change in the momentum of the system will occur? Yes, always. the momentum of the cannon is equal to the magnitude of the momentum of the cannon ball and points in the opposite direction.

Gravitational interactions are always attractive and depend on the masses of interacting objects. There is a gravitational force between any two masses, but it is very small except when one or both of the objects have large mass.

There are four interactions known to science, they are called gravity, electromagnetism, weak and strong. These interactions often manifest themselves as forces between particles. The gravitational interaction, for example, is responsible for the attractive force between masses.

gravitational interaction in British English or gravitational force. an interaction between particles or bodies resulting from their mass. It is very weak and occurs at all distances. See interaction (sense 2)

Since energy and mass are equivalent, all forms of energy (including light) cause gravitation and are under the influence of it. The equation illustrates that the larger the masses of the objects or the smaller the distance between the objects, the greater the gravitational force.
