Question 56

Gravity is responsible for the formation of the solar system.

The gravitational force played a crucial role in the formation of the solar system, as it caused the dust and gas in the solar nebula to collapse and coalesce into larger bodies, ultimately forming planets and other celestial objects.

A) Charge

Charge refers to the electromagnetic force that affects particles with electric charge. While it plays a role in atomic and molecular interactions, it is not a primary factor in the gravitational processes that led to the formation of the solar system.

B) Friction

Friction is a force that opposes the relative motion of two surfaces in contact. In the context of solar system formation, friction may occur during the accretion process, but it is not a driving force in the initial collapse of the solar nebula, making it an irrelevant factor in this context.

C) Heat

Heat is a form of energy that can influence the behavior of matter, but it does not directly cause the formation of the solar system. While heat generated from gravitational collapse can affect the state of matter, it is gravity that initiates the process of coalescence and formation.

D) Gravity

Gravity is the fundamental force that governs the attraction between masses. In the formation of the solar system, gravity caused the initial dust and gas to clump together, leading to the formation of the sun, planets, moons, and other celestial bodies through a process known as accretion.

Conclusion

Gravity is definitively the correct answer as it is the key force that initiated the formation of the solar system by pulling together matter from the solar nebula. Other options, such as charge, friction, and heat, do not play a fundamental role in the gravitational processes necessary for the formation of celestial bodies, making them incorrect in this context.
