When you hold a textbook and a pencil, why does the textbook feel heavier than the pencil?
A Your hand repels the textbook with less force.
B The textbook has a stronger attraction to Earth.
C You can grip the pencil with more strength.
D The textbook has less mass than the pencil
B The textbook has a stronger attraction to Earth.
The correct answer is D: The textbook has less mass than the pencil.
The sensation of weight is determined by the object's mass and the force of gravity acting on it. The more massive an object is, the more gravitational force it experiences, and therefore, the heavier it feels. In this case, even though the textbook may appear larger in size, it has less mass compared to the pencil. Therefore, when you hold both objects, the pencil will feel lighter and the textbook will feel heavier.
The correct answer is D - The textbook has less mass than the pencil.
To understand why the textbook feels heavier than the pencil, we need to consider the concept of mass. Mass is the amount of matter an object contains, which determines how much force is required to accelerate or move it. In simple terms, objects with more mass require more force to move or lift.
In this scenario, even though the textbook may be physically larger in size, it has less mass compared to the pencil. When you hold the textbook and the pencil, you are essentially applying an upward force against the downward force of gravity. Since the textbook has less mass, it requires less force to counteract the force of gravity. As a result, you may feel the textbook as heavier because you are exerting more force to hold the pencil, which has more mass compared to the textbook.
Option A, "Your hand repels the textbook with less force," is not a relevant factor in the weight perception of the textbook compared to the pencil.
Option B, "The textbook has a stronger attraction to Earth," is not accurate because the strength of gravity is the same for both objects. The difference lies in the mass, not the strength of attraction.
Option C, "You can grip the pencil with more strength," may allow you to hold the pencil more firmly, but it does not directly affect your perception of weight. The weight is determined by the mass of the objects, not by the strength of your grip.
Therefore, the correct answer is D - The textbook has less mass than the pencil.
