Question 24

All physical objects are attracted to one another by the force of gravity.

Gravity is the universal force that causes all physical objects with mass to attract each other, regardless of their size or distance apart.

A) The force of gravity

This option is correct because gravity is the fundamental force responsible for the attraction between all masses. It operates over vast distances and is a key principle in understanding the motion of celestial bodies and objects on Earth.

B) Inertia

Inertia refers to the tendency of an object to resist changes in its state of motion. While it is a key concept in physics, it does not describe the attraction between objects. Instead, inertia explains why objects continue moving or remain at rest unless acted upon by a force.

C) Acceleration

Acceleration is the rate of change of velocity of an object. It results from the application of force but does not itself account for the attraction between masses. Thus, acceleration is not a force that draws objects together, but rather a consequence of forces acting upon them.

D) Magnetic force

Magnetic force pertains to the attraction or repulsion between charged particles or magnetic materials. While it can attract certain types of objects, it is not a universal force applicable to all physical objects, making it an incorrect choice in this context.

Conclusion

The force of gravity is the only option that universally applies to all physical objects, explaining their attraction to one another. Inertia, acceleration, and magnetic force do not represent the fundamental principle of attraction between all masses, thereby confirming that gravity is the definitive and correct answer.
