Attraction in physics is a fundamental force that arises between objects due to their mass or electric charge. It follows the principle of gravity, where objects with mass exert an attractive force on each other, while charged objects can attract or repel each other based on their electric charges.
Response to the query in detail
Attraction in physics is governed by fundamental forces that arise between objects due to their mass or electric charge. One of the most well-known forces of attraction is gravity, which is responsible for the movement of celestial bodies, the tides, and our weight on Earth. Gravity follows Isaac Newton’s law of universal gravitation, which states that any two objects with mass exert an attractive force on each other, directly proportional to the product of their masses and inversely proportional to the square of the distance between them. As Newton famously described, “I can calculate the motion of heavenly bodies, but not the madness of people.”
In addition to gravity, attraction can also occur between electrically charged objects. Oppositely charged objects attract each other, while objects with the same charge repel each other. This interaction is described by Coulomb’s law, which states that the force of attraction or repulsion between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Here are some interesting facts about attraction in physics:
- Gravity is an incredibly weak force compared to the other fundamental forces, such as electromagnetism and the strong and weak nuclear forces.
- The law of gravitation can be applied not only to massive objects like planets and stars, but also to everyday objects on Earth. It is what causes objects to fall when dropped.
- The discovery of gravity is often attributed to Sir Isaac Newton, who formulated the laws of motion and universal gravitation in the late 17th century.
- Albert Einstein’s theory of general relativity revolutionized our understanding of gravity by describing it as the curvature of spacetime caused by massive objects.
- Electromagnetic attraction and repulsion play a crucial role in everyday life, from the functioning of electronic devices to the chemistry of atoms and molecules.
- Unlike gravity, which only attracts, electric charges can attract or repel based on their polarity.
- The electromagnetic force is about 10^36 times stronger than the force of gravity. This enormous difference explains why gravity is usually overshadowed in our daily experiences by other forces.
While it is not possible to include a table directly in this text format, here is an example table showcasing the fundamental forces and their relative strengths:
| Fundamental Force | Relative Strength compared to Gravity |
|---|---|
| Strong Nuclear Force | 10^38 times stronger |
| Electromagnetic Force | 10^36 times stronger |
| Weak Nuclear Force | 10^25 times stronger |
| Gravity | Base reference force |
In conclusion, attraction in physics is an essential concept that arises from fundamental forces such as gravity and electromagnetism. Understanding these forces helps us comprehend the behavior of objects at both cosmic and atomic scales, enabling us to explore the wonders of the universe and push the boundaries of scientific knowledge.

The YouTube video “The science of attraction – Dawn Maslar” discusses how attraction is determined by the brain, with five senses playing a role. The eyes, nose, ears, and touch are all important in determining attraction, and the first kiss is described as a critical moment that can make or break the attraction.

The attraction occurs when two objects of opposite charge are in close proximity, and the electrical force causes these objects to attract. Therefore, positive and negative charges will attract each other.
In physics, attraction and repulsion are characteristic of non-contact forces experienced by two objects when they are moved towards or away from each other. Electric and magnetic forces are examples of non-contact forces that can be either attractive or repulsive. The Law of Attraction operates on the principle of “like attracts like”. According to this principle, everything in the universe is made up of equal masses, such as particles, molecules, and stars.

The Law of Attraction operates on the principle of “like attracts like.” According to this principle, everything in the universe is made up of equal masses, such as particles, molecules, and stars. Therefore, everything is composed of mass. Atoms, which are made up of protons and electrons, are like particles of matter.
