S. No. Gravitational Acceleration (g) Gravitational Constant (G)
1. Acceleration due to gravity is Gravitational constant is
the acceleration acquired by a numerically equal to the
body due to the Earth's force of attraction between
gravitational pull on it. two masses of 1kg that are
separated by a distance of 1 m.
2. g is a vector quantity. G is a scalar quantity.
3. It is different at different The 'G' is a universal constant i.e., its
places on the surface of value is the same (i.e., 6.7 x 10⁻¹¹ N
the Earth. Its value also m² kg²) everywhere in the universe.
varies from one celestial
body to another.
