Question

How many types of gravity are there?

Answer 1

Hint:In order to solve this question, we are going to firstly define the gravity and explain it mathematically then, the equation for gravitational force is given and it is discussed about the types of gravity and the reason for the existence of those types and the properties of gravitational forces.

Formula used: The gravitational force is given by the formula:
\[F = \dfrac{{G{m_1}{m_2}}}{{{r^2}}}\]
Where, \[G\]is the Gravitational constant, \[{m_1}\]and \[{m_2}\]are the masses of the two bodies and \[r\]is the distance between the two masses.

Complete step-by-step solution:
Gravity is the gravitational force which is the force of attraction between two bodies that depends on the product of the masses of the bodies and is inversely proportional to the square of the distance between the bodies.
The gravitational force is given by the formula:
\[F = \dfrac{{G{m_1}{m_2}}}{{{r^2}}}\]
Where, \[G\]is the Gravitational constant, \[{m_1}\]and \[{m_2}\]are the masses of the two bodies and \[r\]is the distance between the two masses.
There is only one type of gravity. There are no other types of gravity present in nature. This means there is only one type of gravitational force that pulls the two bodies together based on their masses and the distance between their centers. Gravity is a type of central force and is the weakest force known in nature. It follows the inverse square law. It is a universal attractive force and there are no other types in which it is classified.

Note:It is to be noted that with the advancement in science and research, it may be possible that there are some types of gravitational waves called LIGO but it hasn’t formed a theory yet. So, in theory and practice we consider that there is only one type of gravity and is not classified into various different types.
