Answer:
Geavity
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.
free fall
The falling of a body from a height towards the earth under gravitational force is called Free fall. Such a body is called freely falling body. ... The acceleration of an object falling freely towards the earth does not depend on mass of object. During free fall,heavier as well as light objects accelerate at same rate.
