@Vaidehi09

OpenStudy (anonymous):

for objects dropped in the air there would be air resistance (friction) and gravitation, in vacuum there is gravitation only

OpenStudy (anonymous):

in air, there'll be the weight of the body vertically downwards and the air resistance vertically upwards.in vacuum, there won't be any air resistance.

OpenStudy (anonymous):

Gravity affects all masses equally.
