Physics Home Tutors in Cavalry Ground Lahore

In everyday air, a feather falls slower than a stone because air resistance matters more for the light, spread-out object. In a vacuum — or when drag is negligible — acceleration due to gravity is the same for both. Mass cancels out of the free-fall equation.

Galileo’s insight was not that air never matters, but that gravity itself does not prefer heavy objects. Demo videos of a feather and hammer on the Moon make the point vivid.

Physics tutors in Cavalry Ground Lahore can separate “gravity” from “air resistance” with one table of two cases: with air and without.
