The term “định Luật Vạn Vật Hấp Dẫn Tiếng Anh” translates to “Newton’s Law of Universal Gravitation” in English. This fundamental law describes the attractive force between any two objects with mass. It’s a cornerstone of physics, explaining everything from the apple falling from a tree to the orbits of planets. We’ll delve into the specifics of this law, exploring its equation, applications, and historical context.
What is Newton’s Law of Universal Gravitation?
Newton’s Law of Universal Gravitation states that every particle in the universe attracts every other particle with a force proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This means that the greater the mass of the objects, the stronger the gravitational force between them. Conversely, the further apart the objects are, the weaker the force becomes. This inverse square relationship is crucial for understanding the dynamics of celestial bodies.
This law has profound implications for our understanding of the universe. It explains why planets orbit stars, why moons orbit planets, and why objects fall to the ground. It’s a foundational concept in physics and astronomy.
The Formula and its Components
The law is mathematically represented by the following equation: F = G (m1 m2) / r^2. Let’s break down each component:
- F: Represents the force of gravity between the two objects.
- G: Is the gravitational constant, a fundamental constant in physics.
- m1 and m2: Are the masses of the two objects in question.
- r: Represents the distance between the centers of the two objects.
This simple equation allows us to calculate the gravitational force between any two objects with known masses and separation. It’s a powerful tool for understanding the interactions between objects in the universe.

Historical Context and Impact of Newton’s Law
Isaac Newton formulated this law in the late 17th century. It revolutionized our understanding of the universe, providing a unified explanation for celestial and terrestrial motion. Before Newton, these phenomena were considered separate and unrelated. Newton’s work laid the foundation for classical mechanics and significantly influenced the development of physics and astronomy.
