Newton’s Law of gravitation

Newton’s Law of gravitation

Statement:

"Every two objects in the universe attract every other object with a force which is directly proportional to the product of their masses and inversely proportional to the square of distance b/w their centres".

Explanation: 

Consider two objects A and B of masses m₁ and m₂ respectively, separated by a distance (d). The gravitational force of attraction b/w these bodies are F.

Mathematical portion: 

According to the law of gravitation we came to know

Where G is the proportionality constant called universal gravitational constant whose value is 6.67 × 10^-11 NM² Kg ^-2. The negative sign indicates that gravitational force is always attractive force. So,  the magnitude of gravitational force can also be written as

why we cannot feel gravitational force among us or with surrounding although everything is matter?

 As the value of G is 6.67 × 10^-11 NM² Kg ^-2. This is very very small. So due to v very small value of G the gravitational force among us is also small and that’s the reason that we cannot feel this force among us.
