Q. 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?
The gravitational force acting is definitely more in the case of a heavier object than a light object but the acceleration depends on the ratio of the force acting on the body to the mass of the body and since gravitational force acting on a body is proportional to its mass the acceleration due to gravity is the same for all bodies irrespective of their masses.
