Why the gravity exist?

Answer 1

We have gravity so that we can walk on Earth. If we didn't have any gravity we would have been floating on Earth. Gravity pulls us towards Earth. and if there was no gravity we would probly die because we would be turning upside dwn and things lil,enthat

Answer 2

There is gravity on earth because of the planet's mass. For example, the moon has lesser gravity because the mass of the moon is less. if you went to jupiter, the gravity there is about 21/2 times as much as the earth's.

Gravity (gravitational force) is a force which arises due to a mass being placed in a gravitational field. All masses have a gravitational field, which means that there is a force of attraction between two masses. Since the earth is a massive body, its gravitational field is considerable and the gravity on a body placed at the surface of the earth can be detected.

Answer 3

Any object in the Universe attracts (through the force called gravity) any other object. Specifically, this force does not depend on being "in space" or not. For example, it is not affected by the presence of an atmosphere (except that the atmosphere has some mass of its own, and might therefore add to the gravitational attraction). However, the force gets weaker at a greater distance.

Answer 4

Unless you are conducting an experiment, people really don't USE gravity, it has always been here on the earth. Humans need gravity to stay on the earth. Without gravity I guess you can say that will will float out into space. It even keeps the earth in orbit with the sun, brings water down for us to survive, and it keeps everything that we own in place, not including balloons of course. (:

Answer 5

Gravity exists because the Earth has mass. If the Earth was massless, gravity would not exist and people would freely float away into space. Acceleration due to gravity is always -9.81 m/s^2 on Earth.

Answer 6

The earth has mass, and that's why it has gravity. Mass begets gravity. Anything with mass automatically has gravity. Gravity is the "dent" in spacetime made by a mass.

Answer 7

Everything that has mass, has a gravitational pull.

The Earth, the Moon, you, me, everything with mass has gravity.

Answer 8

anything with mass has gravity, if it's made of some type of matter, then it has mass which gives it gravity. pretty simple

Answer 9

Every speck of mass in the universe is attracted to every other

speck of mass by a force of gravity, everywhere, all the time.

Answer 10

We need to pee
