Gravity is a fundamental force of nature that is present everywhere in the universe. It is the force that pulls two objects towards each other. The gravitational force is always attractive and acts between all bodies in the universe. Let's understand this concept in detail.

What is the Gravitational Force?

The gravitational force is the force of attraction between any two objects in the universe. It is a force that acts between any two masses, whether they are large or small, near or far. The strength of the gravitational force depends on the masses of the objects and the distance between them.

All Bodies in the Universe Experience Gravitational Force

The gravitational force is present everywhere in the universe. It acts on all the bodies in the universe, whether they are planets, stars, asteroids, or comets. Even the smallest objects have gravitational force acting on them. This means that the correct option is D, which states that gravitational force acts on all bodies.

Gravity on Moon, Other Planets, and Earth

Gravity is present on the moon, other planets, and earth. The strength of gravity depends on the mass of the object and the distance from the center of the planet. The gravity on the moon is weaker than on earth, which is why objects weigh less on the moon. Similarly, the gravity on other planets varies depending on their mass and the distance from the sun.

Conclusion

In conclusion, the gravitational force is present everywhere in the universe, and it acts on all bodies, whether they are large or small, near or far. The strength of the gravitational force depends on the masses of the objects and the distance between them. Therefore, the correct answer is option D, which states that gravitational force acts on all bodies.
