Does gravitational force have a limit?

No. The attractive force called gravity does not extend beyond galaxy groups. If you look at Newton’s Law of Universal Gravitation, you see that the force of gravity on one mass due to another mass depends on their separation r according to the dependence 1/r2.

Is gravitational force an attractive or repulsive force?

Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.

What are repulsive forces?

Definitions of repulsive force. the force by which bodies repel one another. synonyms: repulsion. Antonyms: attraction, attractive force. the force by which one object attracts another.

Is gravitational force a non central force?

Gravitational force is a central force i.e., it acts along the line joining the centres of the two bodies.

Which force is opposite to gravitational force?

normal force
As normal force is the opposite of the gravitational force, we can see that .

Which force is repulsive force?

Repulsive force (magnetism) between magnets of opposite orientation. A compressed material repelling bodies on both sides, e.g. according to Hooke’s law. Repulsive force (biology), associated with involuntarily vomiting, as in response to ingestion of a toxin.

What is repulsive force in chemistry?

Chemical bonds contain forces of attraction and repulsion. Repulsive forces occur only when atoms are very close to each other. The electromagnetic force of repulsion between protons is resisted by strong forces. The strong force holds the protons together to form the nucleus, like “glue”.

Why gravitational force is central force?

Therefore, the gravitational force is a central force since its magnitude is proportional only to the distance between the two particles (where one of the particles can be considered as the center of force), and its direction is along the line joining them (toward the center of force).

Why is gravitational force and Coulomb force called central force?

According to the universal law of gravitation, the force of attraction between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between their centres. Since the force is dependent on the centres of the bodies, it is also referred to as the Central Force.
