Is it possible for any object not to be under the influence of gravity while on Earth?C Stuart Hardwick :
No .
No object can head for the hills the influence of gravityanywhere in the universe , as far as we have intercourse .
It is , however , possible for an target to scarper certain effect of gravity under certain circumstances . Airplanes , for example , scarper the quickening of gravity by constantly expending energy to climb against it . I do it by pressing the electron in the proscribed shells of the mote of my shoe leather against those of the sidewalk .
Skydivers can do something jolly interesting by don their air current - repellent gear and float above a giant fan .
Mythbustersdid essentially the same affair with a penny and an adjustable blower :
And of course , ships and balloon surmount the drag of gravity via buoyancy :
cosmonaut escape more — but not all — burden of gravity by coasting away from the Earth in a unbowed line at exactly the speed they are falling toward it . This is what we call “ being in orbit . ” The same thing can be achieve in an aircraft by carefully diving toward the ground along at on the dot the stop number of acceleration due to gravitational force . pluck up after a few seconds is extremely recommended .
But all these stay under the influence of somberness , and would persist so even if the Earth were n’t here , because there are stack of other physical object , such as the Sun , which also rise their own far - reach gravitational field .
