What is the Difference Between g and G?
🆚 Go to Comparative Table 🆚The main differences between G and g are as follows:
- Definition: G is the gravitational constant, a fundamental constant in physics that appears in Newton's law of universal gravitation. On the other hand, g is the acceleration due to gravity, a measure of how quickly objects accelerate toward the Earth's surface due to the force of gravity.
- Symbol: G is represented by the symbol "G," while g is represented by the symbol "g".
- Value: The value of G is approximately $$6.67430 \times 10^{-11}$$ m³/kg/s², while the value of g is approximately 9.81 m/s² near the surface of the Earth.
- Dependence: G is a universal constant and does not change with location or objects involved. In contrast, g varies with location and is stronger closer to the Earth's center.
- Role: G determines the strength of the gravitational force between two objects with mass. Governs the acceleration experienced by objects in a gravitational field, such as near the Earth's surface.
The relationship between G and g is given by the equation $$g = \frac{GM}{R^2}$$, where g is the acceleration due to gravity, M is the mass of the massive body, and R is the radius of the massive body. Although there is a formula to express the relation between g and G, there is no direct correlation between the two quantities, as the value of G is constant.
Comparative Table: g vs G
The difference between g
and G
in the context of MySQL lies in the way they terminate a query. Both g
and G
are used as terminators for SQL commands in MySQL, but they have distinct functions:
\g
: This sequence is a shorthand version of the semicolon command terminator (';'). It is used to terminate a query and start a new one. It is equivalent to the semicolon and may be used interchangeably.\G
: This sequence also terminates a query, but it returns the result set in a vertical format, which can be easier to read when the number of returned columns is large.
Here is a table summarizing the differences between g
and G
in MySQL:
Terminator | Description | Function | Format |
---|---|---|---|
\g |
Semicolon shorthand | Terminates a query and starts a new one | - |
\G |
Vertical result set format | Terminates a query and returns the result set in a vertical format | Vertical |
