Definition
- Noun:
- (Physics) The universal constant relating force to mass and distance in Newton's law of gravitation: The constant of gravitation is a fundamental physical constant that appears in Newton's law of universal gravitation. It quantifies the strength of the gravitational force between two objects.
Usage
- The constant of gravitation is used in physics to calculate the gravitational force between two masses.
- It is a key component in equations describing celestial mechanics, orbital motion, and gravitational fields.
- It is typically denoted by the symbol G.
Examples
- Noun:
- Newton's law of universal gravitation includes the constant of gravitation, G.
- The precise value of the constant of gravitation is difficult to measure experimentally.
- Calculating the force between Earth and the Moon requires the constant of gravitation.
Advanced Usage
- "The gravitational constant": This is a common synonym for the constant of gravitation.
- The gravitational constant is one of the least precisely known fundamental constants.
Variants and Related Words
