In space, small particles of matter can join together to form larger particles. Those larger particles have more mass and can then attract even more particles to themselves to grow even larger. Eventually, they may form an asteroid, comet, planet, or star. Which force allows the particles to attract more and more particles as their mass increases?

Frictional force arises from the interaction between surfaces in contact and opposes motion. While friction can play a role in the movement of particles, it does not facilitate the attraction of particles to form larger masses in space. Instead, it serves to slow down or resist movement, which is contrary to the process of accumulation described in the question.

Magnetic force is the attraction or repulsion between magnetic objects and is dependent on their charge and orientation. While magnetic forces can influence certain particles, they do not universally apply to all matter in the same way gravitational forces do. Most celestial bodies do not exhibit significant magnetic properties that would facilitate the accumulation of mass as described.

Electrical forces arise from charged particles and can either attract or repel based on their charges. While electrical interactions can influence the behavior of particles, they are not the primary force driving the accumulation of mass in space. Gravitational force is the dominant force at play in the formation of large celestial bodies.
