What is the function of gravity?

Answer 1

Pulls things to the ground.
Drop an apple two yards above your head. Observe how you feel. The apple hit you pretty hard didn't it?! That's gravity. In space the apple would just float around and not come straight at you.

Answer 2

If your talking about the Earth, Moon, and Sun, then the purpose for gravity is so that the planets to go out of balance and crash into other planets!

If you are talking about people, then the role of gravity then is that we don't go bouncing all over the place!

Answer 3

Gravity permeates all of space. Gravity may be weak or strong, but it is everywhere.

Space has no effect on gravity as such but distance does. Gravity decreases as the square of the distance between two objects. An object one million kilometers away will feel four times the gravitational force from and object that an object two million kilometers would feel.

Gravity is a force of attraction between objects with mass, so yes technically you are actually attracting the objects near by to you, but those objects have friction and other forces to stop them from moving. In space, as long as you are far way from object with large mass (planets, stars, moons etc) you will simply either float or continue in a straight line motion (Newton's First Law of Motion).

Answer 4

Gravity is the force that pulls things towards other objects. Like planets gravitational pull is from the core. The core of the planet pulls objects toward it but the ground protects us from reaching it.And

Answer 5

It pulls objects down to earth. It prevents humans/objects from floating.

Answer 6

Gravity is the force that holds us on the earth. It pulls us down all the time we're on or above our home planet.

Answer 7

Gravity on the earth pulls everything down to earth fast.
