Ethan is helping his father rearrange the furniture in their living room. They have two different tables that are the same size. When Ethan pushes on each table, he finds that it is harder to move table A than it is to move table B. Why does Ethan have to push with more force on table A than on table B?
a
Table A has more mass than table B.
b
Table A weighs less than table B.
c
Table A has more volume than table B.
d
Table A is less dense than table B
a
Table A has more mass than table B.
The difficulty Ethan experiences in moving table A compared to table B, assuming both tables are the same size and shape and are being moved across the same surface, is likely due to table A having more mass. More mass means that table A has more inertia (resistance to change in motion), and thus requires a greater force to accelerate it from rest or to overcome static friction between the table and the floor.
