Universal Gravitational Constant
Definition: The "universal gravitational constant" is a special number used in physics. It helps us understand how gravity (the force that pulls things together) works between two objects based on their masses (how heavy they are) and the distance (how far apart they are) between them.
Easy Explanation:Think of the universal gravitational constant as a key number that tells us how strong gravity is. If you have two objects, like the Earth and the Moon, this constant helps calculate how much they pull on each other because of their mass and the distance between them.
Usage Instructions: The term "universal gravitational constant" is often used in scientific discussions about gravity. You can use it when talking about physics, astronomy, or any topic that involves forces and objects in space.
Example: - "The universal gravitational constant is important for calculating the orbits of planets around the Sun."
Advanced Usage: In advanced physics, the universal gravitational constant is often represented by the letter ( G ) and has a specific value of approximately ( 6.674 \times 10^{-11} \, \text{N(m/kg)}^2 ).
Word Variants: - Gravitational Constant (a shorter way to say it) - Gravitation (the force itself, related to how the constant is used)
Different Meanings:In this context, the universal gravitational constant specifically refers to the number used in the law of gravitation. It doesn’t have different meanings outside of physics.
Synonyms:There are no direct synonyms for "universal gravitational constant," but you might hear "gravitational constant" used in similar contexts.
Idioms and Phrasal Verbs:There aren’t any idioms or phrasal verbs specifically related to the universal gravitational constant, as it is a technical term used mostly in scientific language.
Summary: The universal gravitational constant is a crucial concept in physics that helps describe the force of gravity between two masses.
