Nikhil bought a large plant in a planter for his mother. He took it home and pushed it around his living room until he found a good location for it near the window. After he watered the plant, he was very surprised how difficult it was to push the planter. Based on Newton’s second law, why does it become more difficult to move the planter? Choose the three statements that apply.

Newton's 3rd law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.  This applies to this situation because, the object got heavier as he added more weight to it,  that caused it to become more difficult to move.
