When you hold a textbook and a pencil, why does the textbook feel heavier than the pencil? (1 point)
A. You can grip the pencil with more strength.
B. The textbook has less mass than the pencil.
C. Your hand repels the textbook with less force.
D. The textbook has a stronger attraction to Earth.
D. The textbook has a stronger attraction to Earth.
To determine why the textbook feels heavier than the pencil, we need to consider the factors that contribute to the sensation of weight. Weight is a measure of the force exerted on an object due to gravity. This force depends on two factors: the mass of the object and the acceleration due to gravity.
In this case, let's assume that the mass of the textbook and the pencil is the same. Now, the only factor that can cause the textbook to feel heavier is the acceleration due to gravity.
Gravity is a force that attracts objects towards the center of the Earth. The strength of this force depends on the mass of the object. Since we assumed that the textbooks and the pencil have the same mass, we can exclude options B and D.
Now let's consider options A and C. Option A suggests that the grip strength affects the feeling of weight. However, our grip strength doesn't contribute to the weight of the objects. It only affects our ability to hold and manipulate them.
Option C refers to the repelling force exerted by our hand on the objects. However, our hand does not repel objects in this scenario, as there is no force pushing the objects away.
Based on the explanations above, the most accurate answer is B. The textbook feels heavier than the pencil because it has more mass.
D. The textbook has a stronger attraction to Earth.
The weight of an object is determined by its mass and the force of gravity pulling on it. The textbook, being larger and having more mass, has a stronger gravitational attraction to Earth compared to the pencil. As a result, it feels heavier when held in the hand.
