theory of gravitation
Học thuậtThân thiện
Definition
- Noun:
- A scientific theory describing gravitational attraction: The theory of gravitation is a fundamental physical theory which states that any two particles of matter attract each other with a force. This force is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Usage
- The theory of gravitation is used to describe and predict the gravitational interactions between objects with mass.
- It is a core concept in physics, astronomy, and engineering for understanding phenomena from falling apples to planetary orbits.
Examples
- Noun:
- Newton's theory of gravitation successfully explained the motion of the planets.
- The theory of gravitation is essential for calculating satellite trajectories.
Advanced Usage
- "within the framework of the theory of gravitation": used to specify that an explanation or calculation is based on this specific theory.
- Kepler's laws of planetary motion can be derived within the framework of the theory of gravitation.
Variants and Related Words
- Law of universal gravitation: Often used synonymously with "theory of gravitation," specifically referring to Newton's formulation.
- Newton's law of universal gravitation is a specific form of the theory of gravitation.
- Gravitational theory: A more general term that can encompass Newtonian gravity, Einstein's general relativity, and other models.
- Einstein's general relativity is a modern gravitational theory.
Synonyms
- Law of universal gravitation (specifically Newton's formulation).
- Newtonian gravity.
Related Concepts
- General relativity: A more comprehensive theory that supersedes Newton's theory of gravitation in describing gravity as the curvature of spacetime, especially under strong gravitational fields or at high velocities.
- For most everyday calculations, Newton's theory of gravitation is sufficient, but general relativity provides a more accurate description of the universe.
- Gravity: The natural phenomenon of attraction between physical bodies, which the theory of gravitation seeks to explain.
Noun
- (physics) the theory that any two particles of matter attract one another with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them
