The gravitational force is a force that attracts any two objects with mass..

Gravitational force is one of the fundamental forces of nature that exists between any two objects with mass. This force is responsible for the attraction of objects towards each other and is the reason why everything on Earth stays in place. It is governed by the law of gravitation, which was discovered by Sir Isaac Newton in the 17th century.

**The law of gravitation**

The law of gravitation states that the force of attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This means that the greater the mass of the objects and the closer they are to each other, the stronger the gravitational force between them will be. The formula for the gravitational force is F=G(m1*m2)/r^2, where F is the force of attraction, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between them.

**Examples of gravitational force**

Gravitational force is responsible for many phenomena in the universe, including:

- The Earth's gravitational pull on objects, which keeps them from floating away into space.
- The gravitational force between the Sun and planets in our solar system, which keeps them in their orbits.
- The gravitational pull of the Moon on the Earth, which causes tides in the oceans.
- The gravitational force between stars in a galaxy, which keeps them from flying apart.

**Conclusion**

In conclusion, gravitational force is a fundamental force of nature that exists between any two objects with mass. It is responsible for the attraction of objects towards each other and is governed by the law of gravitation. This force is responsible for many phenomena in the universe, from keeping planets in their orbits to causing tides in the oceans. Understanding the nature of gravitational force is essential in our understanding of the universe and how it works.
