Question

If the gravitational force acts on all objects in proportion to their masses, why a heavy object does not fall faster than light object?

Answer 1

The acceleration they experience is independent of their mass.

Therefore, all objects fall on the ground with the same acceleration known as acceleration due to gravity.

$a=\text{g}$ for Earth $=\text{9.8}m{s}^{-2}$

Thus, a heavier object does not fall faster than a lighter object.
