g and G, The differences. Class 9

 

The acceleration due to gravity (g) 

1. It is the acceleration caused by the gravitational force.

2. Its value depends on the mass and radius of a planet or heavenly body.

3. Its value changes from place to place.

4.Its a vector quantity.

The universal gravitational constant(G)

1. It is numerically equal to the force of attraction between two bodies each of mass 1kg separated by distace of 1m.

2. Its value does not depend on the mass and size of bodies. 

3. Its value is constant everywhere in the universe. 

4. It's a scalar constan.
