A student is moving furniture. Even though table A and table B are the same size, table A requires more force to move. Why?
Table A has greater volume compared to table B.
Table A has a greater mass than table B.
Table A has less density than table B
Table A has less weight than table B.
Table A has a greater mass than table B.
The correct answer is: Table A has a greater mass than table B.
When it comes to moving furniture, the force required is directly related to the mass of the object. If two objects, such as table A and table B, have the same size but different masses, the one with the greater mass will require more force to move. In this scenario, table A requires more force because it has a greater mass compared to table B.
The reason that table A requires more force to move, even though it has the same size as table B, could be due to a couple of factors. Let's break down each option:
1. "Table A has greater volume compared to table B": The volume of an object refers to the amount of space it occupies. However, the volume alone does not determine the force needed to move an object. So, this option may not necessarily be the reason.
2. "Table A has a greater mass than table B": Mass is the amount of matter in an object. In a scenario where two objects have the same size but different masses, the object with a higher mass will require more force to move. Therefore, this could explain why table A needs more force to be moved.
3. "Table A has less density than table B": Density is defined as mass divided by volume. If table A has less density than table B, it means that it has less mass packed within the same volume and, therefore, may require less force to move. So, this option doesn't seem to be the explanation.
4. "Table A has less weight than table B": Weight is the force exerted on an object due to gravity. If table A has less weight than table B, this could indeed explain why more force is needed to move table A. However, weight is directly proportional to mass, so if table A has a greater mass (as mentioned in option 2), it will also have a greater weight.
Considering the above explanations, the most likely reason for table A requiring more force to move, even though it is the same size as table B, is because table A has a greater mass than table B (option 2).
