The force of attraction is called gravity. It is the force that exists between any two objects with mass and pulls them towards each other.

The force of attraction between two objects is known as gravity. It is a fundamental force that exists between any two objects with mass and pulls them towards each other. The concept of gravity has intrigued scientists, philosophers, and thinkers throughout history. As the renowned physicist Albert Einstein famously stated, “Gravity is not responsible for people falling in love.”
Here are some interesting facts about gravity:
-
Universal force: Gravity is a universal force that acts upon all objects in the universe. From a tiny particle to a massive star, gravity plays a significant role in shaping and governing the structure of the cosmos.
-
Sir Isaac Newton’s law of universal gravitation: In the 17th century, Sir Isaac Newton formulated the law of universal gravitation, which states that every particle attracts every other particle in the universe with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This law mathematically describes the force of gravity.
-
Gravitational field: Gravity can be understood in terms of the gravitational field, which surrounds every object with mass. The gravitational field is the region in which other objects experience the force of gravity. The intensity of the gravitational field decreases with distance from the object.
-
Weight vs. mass: Gravity is often confused with weight, but they are different concepts. While gravity refers to the force of attraction between objects, weight is the measure of the gravitational force acting on an object. Weight depends on the mass of an object and the strength of the gravitational field it is in.
-
Escape velocity: The concept of escape velocity is closely related to gravity. Escape velocity is the minimum velocity an object needs to escape the gravitational pull of a planet or celestial body. For example, to leave Earth’s gravity, an object must reach a velocity of approximately 25,020 miles per hour or 40,270 kilometers per hour.
Now, let’s illustrate the gravity of different celestial bodies by presenting a table:
| Celestial Body | Gravity (m/s²) |
|---|---|
| Earth | 9.8 |
| Moon | 1.6 |
| Mars | 3.7 |
| Jupiter | 24.8 |
| Sun | 274 |
Please note that the values presented above are approximate and may vary slightly depending on factors such as altitude and location on the celestial body.
In conclusion, gravity is not only a force of attraction but also a fascinating phenomenon that shapes our understanding of the universe. From Newton’s laws to the concept of escape velocity, gravity has captured the curiosity of humanity for centuries, inspiring scientific discoveries and philosophical contemplation alike.
Video response to “What is the force of attraction called?”
In the video, the speaker explains that particles have forces of attraction between them. They give examples to illustrate that the strength of these forces differs between substances. For example, a metal spoon has strong forces of attraction between its particles, making it difficult to break. In contrast, substances like chalk, water, and air have weaker forces of attraction, making them easier to break or cut through. This highlights the varying strengths of attraction forces among different substances.
