It would be very chaotic... For example anything that was not attached to the Earth will probably go flying off into space in a straight linear line. If gravity disappeared the Earth's atmosphere would float into space so other planet's atmospheres would also flow into space. Planets will break apart into pieces and go off in space since planets are held together by gravity.
Imagine gravity is a string... Once you let go that string or quote-unquote "turn off" gravity everything will go flying into linear lines out into the vastness of the cosmos. I hope this helps if you need any more examples for have any other questions please let me know. Have a blessed day. :')
