Show gravitation gravitation is what makij j things seem beav heavy Y it is what keeps us fast to old mother earth so we do riot not bow away off into space if wi wa had no weight we w could not walk it is the earths gravitation that gives us power to put one toot ahead and pull the other along over the ground or to jump a isace space tf f ground the earth weighs two textile tex till ions of tons of course you have no idea of all this immense number but the sun bun weighs about as much as the earth so you may imagine the sun must bean be an enormous world it is about times the size of the earth itis it is about as dense hard as water so if you were there and did not burn up you would sink right into it as you would in the ocein the sun being so much heavier than the earth has an attraction of gravitation 28 times as great as the earth so if you were there and could stand on the face of the sun it would pull you flat down and hold you so tightly you could not get up it would be beja just as imps sible for you to rise up as it would here on the earth if you laid down and some ono one p piled i red pounds weight on you the suns gravity would hold you so BO close no dan g on nw isyou you were oti 1 where the alfr a ebion of eriv gravitation atio n is only one fifth as great as on the earth you would be able to carry nearly a ton on tour shoulders for the woon moon would not pull more than one fifth of the weight on you or on your burden you would be so light you could run and jump fever an ordinary house if you were on some of the asteroids or the moons of mars you could carry a rock as big as a barn and make a jump that would land tou jou clear out of sight because these bodies have so little attraction of gravitation so little weight to pull upon you on jupiter we would weigh two and three quarters times as heavy us as on the earth and it would be all we could do to walk upright it would pull so hard bard upon us if two of you were in the interplanetary of interstellar space you would weigh nothing at all you would stand on nothing and no gravitation would pull you down you would be stationary you could not walk jump nor move along if you were a rod apart you could not get to together 0 ether nor could you get further apart but if there was a line reaching from one to the oth eryou would be able to pull yourselves together then if you cut the line and gave each other a push you would separate and go further and further from each other for no one inoes knows how long or how far but for ever and ever unless you struck some body in space if you were in the interplanetary space of our solar system on looking towards toward the sun run you would see eee it but if you were to look rw the sun bun all would be black and dark as night for there would be no atmosphere to diffuse the rays of light you would see nothing kut but the sun or stars it would be intensely cold too as it is said to be below zero so BO you would immediately freeze to death and rema remain i n so EO for ages unless some star should gradually pall y draw you into its gery mass fiur sun eun is ie a star and it might amigh t draw you into it you would strike its surface with a velocity of about aso miles a second but being dead that would not hurt you I 1 guess gues you will not be able to try any of these theeo experiments but it is well to know what could and would result if they could be tried selected |
