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

उत्तर
Gravitational force affects all objects in proportion to their mass. However, a heavier object does not fall quicker than a lighter object. This is due to the following:
`"Acceleration" = "Force"/"Mass"`
or Force = Acceleration × Mass
As force is directly proportional to mass, acceleration is constant for a body of any mass.
