Is free fall possible on Earth?
Is free fall possible on Earth? You can get free fall in Earth's atmosphere as long as you move the air along with the falling object. This is how free fall is produced in reduced gravity aircraft. The aircraft itself is not in free fall because it has to use its engines to overcome atmospheric drag.
Do heavier objects fall faster?
Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
