What carries EARTH?

Question

We are forced by gravity on earth, without it we would be floating.
Earth is not floating, it has a systemic movement so do all other planets including the sun. WHAT CARRIES EARTH?

Answer 1

The earth isn't "carried" by anything. Gravity is the force that attracts all matter however it is a very weak force. In fact, if you were floating in space and a few feet away from you was another person you would eventually be pulled together, it would just take a very long time.

Astronomers best guess is that as the sun formed it was surrounded by circulating disks of dust and debris that began to collect together in clumps. As those clumps became more massive their gravity would attract the sourrounding particles and eventually those became planets.

It is the suns gravity, not magnetic field that holds the earth in place. The reason that happens is because the suns gravity is trying to pull the earth closer but the earth is moving due to conservation of angular momentum. (Imagine standing on a very fast merry-go round. If you don't hold on to anything you'll be flung off away from the center but if you grab the rail you will be held in place. The suns gravity is the rail for the earth.)

So nothing carries earth, it is held together by its own gravity and floating in the vacuum of space with it's velocity trying to foce it to fly away but the gravity of the sun tugging back on it.

Answer 2

Fg=mrw^2
w=2π/T
r=radius of earth
T=period

Fg=force due to gravity = G(Me)(m)/r^2
w=omega
m=mass of an object
Me=mass of earth
G=gravitational constant

Fg=mrw^2 GMe/r^3 =(2π/T)^2
4π(r^3) / GMe=T^2
therefore after calculating T, if the period is lesser, than we would float. Hence it can be seen that with gravity also we can float if the day was abt 1.4hrs long instead of 24hrs. The earth or any planets posses an initial velocity and the gravitaional force of attraction between the planets cause the planets to accelerate towards the cetre of the sun and since the planets have an intial velocity , they do no directly move staright in to the sun and they go around the sun which is known as orbits.

And as for the part of what carries earth i'm not too sure but what i think is that all the planets and galaxies are falling at the same speed hence relative to the stars we seem to be floating. example: two particles dropping in a dark hole and both particles seems to be stationary with respect to each particle.

Kudos..nice question

Answer 3

The earth does not have a wearing means. If we had the ability source lets stack human beings severe and wide and help 1000's of situations our present day inhabitants. this is the quantity of power which will be the most suitable reduce. locate the full power output of the solar. assume that we construct a Dyson sphere and seize ever unmarried little bit of the ability output. convert that power right now into tremendous energy. assume a 1200 cal/day weight-relief plan. Do the mathematics then you truthfully have the theoretical max. This assumes that we come across no different source of well-known power except the solar. If we are in a position to tap countless the energies envisioned through countless the wilder string theories then there is not any reduce to the available inhabitants.

Answer 4

It is the gravitational force between the earth and the sun and also the gravitational force of planet Jupitar that gives earth and other planets their systematic movement. It should also be borne in mind that the specific path of the earth around the sun is also determined by the force created by the earth through her revolving around her axis.

Answer 5

The Earth stays in orbit around the Sun due to its gravitaional attraction, just like (as you said) we are held down to the Earth because of gravity.

Answer 6

Gravity creates rotation and this in turn keeps the earth and all the planets navigating around the sun which in turn have the biggest mass and henceforth the biggest attraction.

Answer 7

Wow, many years ago, when as a student I was working a summer job, this old redneck labourer I worked with used to say "there must be a God, because what holds the sun and moon up in the sky?"

Gee, I didn't think people like that still existed.

Answer 8

We are held to Earth's surface by its gravitational field. The Earth goes around the sun, instead of flying off in a straight line, because of the Sun's magnetic field. The solar system as a whole is bound into our galaxy by the aggregate gravitational field of all the bodies in the galaxy, and so on.

Answer 9

Shovels and wheelbarrows carry small quantities of EARTH.

Excavating machines and dump trucks carry larger quantities of EARTH.

Answer 10

what keeps all the electrons in an atom? gravity ofcourse.
