Question

What are the important characteristics of gravitational force?

Answer 1

Gravitational force:

1. According to Newton's universal law of gravitation, every object attracts every other object with a force that is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
2. Mathematically, it can be expressed as:

$F=\mathrm{G}\frac{m_1{m}_2}{r^2}$

Where $F$ is the gravitational force between the two objects, $G$ is a gravitational constant, $m_1$ is the mass of the first object, $m_2$ is the mass of the second object, and $r$ is the distance between the two objects.

Characteristics of gravitational force:

1. It is the weakest non-contact force in nature.
2. It obeys the inverse square law.
3. It is always positive in nature.
4. It is directly proportional to the product of the masses of the two bodies.
