Question 2
Gravitational force acts on all objects in proportion to their masses. Why then, a heavy object does not fall faster than a light object?

Answer 1

The gravitational force F acting on a body of mass m near the surface of earth is given by
$F=G\frac{M\times m}{R^2}$
where R = Radius of the earth
and M = Mass of the earth

=> Acceleration, $g=\frac{F}{m}$ = $G\frac{M}{R^2}$

This value is constant (if we neglect air resistance) and does not depend upon the mass of an object. Hence, heavy objects do not fall faster than light objects.
