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.|
