The greatest increase in the inertia of an object would be produced by increasing the
(1)mass of the object from 1.0 kg to 2.0 kg
(2)net force applied to the object from 1.0 n to 2.0 n
(3)time that a net force is applied to the object from 1.0 s to 2.0 s
(4)speed of the object from 1.0 m/s to 2.0 m/s
