Definition
  1. Proper noun:
    • Newton's law of universal gravitation: A fundamental physical law stating that every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Usage
  • Newton's law of gravitation is used to describe and calculate the gravitational force between two objects. It is a cornerstone of classical mechanics.
    • Astronomers use Newton's law of gravitation to predict the orbits of planets.
    • The apple falling from the tree inspired the formulation of Newton's law of gravitation.
Advanced Usage
  • "To apply Newton's law of gravitation": To use the mathematical formula of the law to solve a problem.
    • To find the force between Earth and the Moon, one must apply Newton's law of gravitation.
  • "Derived from Newton's law of gravitation": A concept or formula that is a logical consequence of the law.
    • The formula for calculating orbital velocity is derived from Newton's law of gravitation.
Variants and Related Words
  • Law of universal gravitation: The full, formal name of the law.
  • Universal gravitation: The general concept that all masses attract each other.
  • Inverse-square law: A term describing how the force decreases with the square of the distance, a key feature of this law.
  • Gravitational constant (G): The proportionality constant in the mathematical formula of Newton's law.
Synonyms
  • Law of universal gravitation (exact synonym)
  • Universal law of gravitation (exact synonym)
Related Phrases
  • Newtonian gravity: The system of gravitation described by Newton's law, as opposed to Einstein's theory of general relativity.
    • For most engineering purposes, Newtonian gravity is sufficiently accurate.
Noun
  1. (physics) the law that states any two bodies attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them
