What is the difference between ‘G’ and ‘g’?
| Gravitational constant (G) | Acceleration due to gravity (g) |
|---|---|
| * It is defined as the force of attraction between two objects of unit mass each separated by unit distance. | * It is defined as the acceleration of an object freely falling under the action of force of gravity. |
| * Universal constant and its value is 6.673×10-11Nm2kg-2. | * Constant at a given place and its value changes from place to place. Mean value of g on surface of earth is 9.8 ms-2. |
