Answer 1

the force that attracts a body towards the centre of the earth, or towards any other physical body having mass is called gravity.

Answer 2

Gravity, or gravitation, is a natural phenomenon by which all things with mass are brought toward (or gravitate toward) one another, including planets, stars and galaxies. Since energy and mass are equivalent, all forms of energy, including light, also cause gravitation and are under the influence of it.
