Small objects are not attracted to each other because their gravitational force is too weak to overcome other forces, such as electromagnetic forces, which dominate at small scales. The gravitational pull between small objects is negligible compared to the forces at play on that scale.
So let us take a closer look at the inquiry
Small objects are not attracted to each other primarily due to the negligible gravitational force between them, as it is too weak to overcome other dominant forces at small scales. While gravity is a universal phenomenon that attracts all objects with mass, including small objects, the effects become increasingly insignificant as the distance between the objects decreases and their masses decrease.
Electromagnetic forces, for instance, play a more significant role at small scales. These forces are much stronger than gravity and govern the interactions between charged particles. The electromagnetic force is responsible for the cohesion between atoms and molecules, which ultimately determine the properties of matter on a macroscopic level. As a result, the attractive forces between small objects due to electromagnetic interactions tend to overpower any gravitational effects.
As Albert Einstein, the renowned physicist, eloquently expressed, “Gravity is not responsible for people falling in love.” This quote beautifully illustrates the notion that gravity has little influence on interactions at the human scale, let alone small objects. While it humorously refers to the concept of love, it effectively conveys the idea that gravity’s impact is often overshadowed by other forces.
Interesting facts regarding the lack of attraction between small objects include:
-
The gravitational force between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them, highlighting the significance of mass and distance in gravitational interactions.
-
Sir Isaac Newton’s law of universal gravitation mathematically describes the attractive force between objects with mass.
-
The dominant force at small scales, electromagnetic force, arises from the interactions between electrically charged particles.
-
Electromagnetic forces govern a vast array of phenomena, including chemical bonding, magnetism, and even the interactions between light and matter.
-
The relative strength of electromagnetic forces to gravity can be illustrated by considering the fact that a small refrigerator magnet can easily overcome the gravitational force exerted by the entire Earth.
While a table may not be applicable in this particular case since the question focuses on the absence of attraction between small objects, it is worth highlighting the contrasting strengths of gravitational and electromagnetic forces.
| Force | Gravitational Force | Electromagnetic Force |
|---|---|---|
| Strength | Weak | Strong |
| Range | Infinite | Finite |
| Interaction | Mass-dependent | Charge-dependent |
| Influence on small objects | Negligible | Dominant |

This video provides a simple explanation of gravity, including its effects on objects and its relation to the law of gravity. The video also explores the differences in views of gravity from Isaac Newton and Albert Einstein. The findings of gravity research have potential implications that are also discussed.
There are several ways to resolve your query
The two objects in a room do not move towards each other because due to their small masses, the gravitational force of attraction between them is very, very weak.
The objects in the room are small and have very less mass comparatively. Hence, the mutual force of attraction between the objects in the room is neglible. Thereby, illustrating that the gravitational force between two small objects having small masses is very weak. Also, the Earth’s gravitational force pulls everything toward the center of Earth.
