Question

Write two properties of gravitational force​

Answer 1

Answer:

Explanation:

Mark me brainlist if helped.

Important properties of gravitational force:

1. It is a universal attractive force.

2. It is directly proportional to the product of the masses of the two bodies.

3. It obeys inverse square law.

4. It is a long range force and does not need any intervening medium for its operation.

5. Gravitational force between two bodies does not depend upon the presence of other bodies.

6. It is the weakest force known in nature.

7. It is a central force (i.e., it acts along the line joining the centres of the two bodies).

8. It is a conservative force (i.e., work done in moving a body against the gravitational force is path independent).

9.Gravitational- force between two bodies is thought to be caused by ah exchange of a particle called graviton.

Answer 2

$\huge\sf{Answer:-}$

• It is the force of universal attraction, that is, it is found between every two bodies present in the universe.

• Its value is proportional to the product of the mass of both bodies and is inversely proportional to the square of the distance.

• This force is weaker than all the forces found in nature, the value of the electric force between two electrons is about 1043 times the force of gravity.
