Question

if i have two balls one i throw from up to down in open area and second in vaccum than which ball come down first?

Answer 1

first ball will come because the gravit y is more and the vacum does not reflect on the vacum

Answer 2

The second ball will come down first.Here gravitational force doesn't matter because it is present everywhere.The only thing which matters here is air resistance.Since a vacuum has no air the second ball will come down first.
