Has the weight of the Earth Changed, if Yes or No Why ?

Answer 1

the earth does not actually have a "weight"

weight is the force that a mass in a gravity field exerts

I assume you mean the mass of the earth.

The mass of the earth is changing all the time, but not by much. Meteorites and space debris are added to the earth's mass constantly.

volatile gasses are escaping from the gravity well that holds the atomsphere and then drift off into space, borne on the "solar wind"

and finally, due to all the energy operations of all the plants, animals, people, and machines, the mass-energy balance on the earth is changing slightly as what was once mass is manifested as energy (e=mC^2)

I bet their are a few other terms to the mass balance of the earth

Answer 2

Weight is a relative measurement and refers to the effect of gravity of one object on another objects mass. The largest gravitational force in the immediate area would be the Sun so... the weight of the Earth on the Sun would be very small due to Earth's motion around the Sun and the motion of the earth it self. Hypothetically If everything in the cosmos stood still like points on a graph(we would all die, but) the points would be brought together slowly at first then quickly as momentum would build. This effect is believed to be caused by gravity's(theoretical) space warping properties. Gravity is actually a very weak forced compared to others and so far is the only force we know of for which no particle has been found.

Answer 3

First, the weight has no earth because there is no gravity in space. Weight equals mass times force of gravity (mg). If you mean the mass, probably not but there is really no way to tell. You can only just accept that the law of conservation of mass is true and has helf all these years.

Answer 4

Every day the earth is bombarded with billions of tons of debris. It lands on our planet and adds weight. We see only a very tiny, einsie wiensie, itty bitty, fraction of this. It is space dust and meteorites. The majority of this debris, upon hitting earth's atmosphere, burn up into gas and dust and gravity keeps it here. Either on the ground or mixed with our air.

Now, we send things into space but that's not enough weight to even matter. The thing to wonder is how much of our atmosphere floats off to space. Air has weight and adds to the total package. I believe it averages out and it stays pretty much the same (give or take).

Answer 5

Yes,but only because we have fired rockets and satellites into space,therefore,the earth ways a bit less.Remember that the earth is a self contained unit in which gravity holds everything together...tom science

Answer 6

yes, because all matter turn into radiation with time, in heavy metals such as uranium it is higher, but still all matter turns into energy and radiation slowly, and after enough time all is gone. so earth mass gets smaller.

another reason is that during space exploration we send stuff up their that is never coming back, so earth mass gets smaller.

finally we have metiers crashing every day, so mass gets bigger, so yes earth mass does change.

even if you light a match, the light escaping from the fire is mass lost!!

Answer 7

No, because matter cannot be created, this means that Earth has weighed the same since it became stable in the universe. There is the same amount of matter that was always here, although it might be in different forms.

Answer 8

no. the weight of meteorites falling down is probably copensated by earth slowly leaking atmosphere into space.

I can't think of any other matter coming to or leaving Earth.
(our sattelites have negligible weight)

Answer 9

no, but the mass has, though a very small amount
