Gravitational Acceleration Difference between mass and weight

Gravitational Acceleration

The earth exerts a costant gravitational pull on a body at any point on its surface.

This gravitational pull will give an uniform acceleration to a free falling body (the body falling freely under the action of gravity ignoring air resistance), increasing its velocity by approximately 9.81 m/s (10m/s) every second.Hence the value of g is approximately 9.8m/s2 (10 m/s2).

Different values of Gravitational accleration (m / s2)
Sun 274.13
Mercury 3.59
Venus 8.87
Earth 9.81
Moon 1.62
Mars 3.77
Jupiter 25.95
Saturn 11.08
Uranus 10.67
Neptune 14.07
Pluto 0.42
