A heavy object falls with same acceleration as a light object during free fall. Choose the correct reason for this effect:
i) ‘g’ is independent of mass
ii) ‘g’ is higher for heavy mass
iii) ‘g’ depends on mass
iv) ‘g’ is higher for light mass

Because the downward force on an object is equal to its mass multiplied by g, heavier objects have a greater downward force. Heavier objects, however, also have more inertia, which means they resist moving more than lighter objects do, and so heaver objects need more force to get them going at the same rate.
