-The acceleration produced in a body due to the force of gravity is called Acceleration due to gravity (g) and its value is 9.8 m/s2.
-Acceleration due to gravity is independent of the shape, size and mass of the body.
-Escape velocity is the minimum velocity with which an object just crosses the earth's gravitational field and never returns. Escape velocity at the earth's surface is 11.2 km/s.
-Escape velocity at the moon's surface is 2.4km/s. Due to low escape velocity, there is no atmosphere on the moon.
- The value of g decreases with height depth from the earth's surface.
- g is maximum at poles.
- g is minimum at the equator.
- g decreases due to the rotation of the earth.
- g decreases if the regular speed of the earth increases if the angular speed of the earth decreases.
- The acceleration due to gravity at the Moon is one-sixth that of the earth.So, the weight of a person on the surface of the Moon will be one-sixth of his actual weight on the earth.

Gravity, also called gravitation, in mechanics, is the universal force of attraction acting between all matter. It is by far the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter.
