When you hold a textbook and a pencil, why does the textbook feel heavier than the pencil?
A.) You can grip the pencil with more strength.
B.) Your hand repels the textbook with less force.
C.) The textbook has less mass than the pencil.
D.) The textbook has a stronger attraction to Earth.
C. The textbook has less mass than the pencil.
D. ........ m g of the book is greater than m g of the pencil
answered, please stop!
The correct answer is D.) The textbook has a stronger attraction to Earth.
Explanation:
The sensation of weight is caused by the force of gravity acting on an object. Both the textbook and the pencil experience the same gravitational force, as they are both influenced by Earth's gravity. However, the perception of weight is influenced by an object's mass. Mass is the amount of matter contained in an object, and it is a measure of an object's inertia or resistance to changes in motion.
Comparing the textbook and the pencil, it is likely that the textbook has a greater mass than the pencil. Therefore, the textbook will feel heavier because it has more mass and thus more inertia. The pencil, on the other hand, has less mass and less inertia, leading to a lighter sensation when held.
The correct answer is C.) The textbook has less mass than the pencil.
Explanation:
Weight is the force exerted by an object due to gravity. When you hold a textbook and a pencil in your hand, both objects experience the same gravitational force pulling them towards the Earth. However, the weight of an object depends on its mass. Mass is the amount of matter an object contains, while weight is the force experienced by that mass due to gravity.
The textbook feels heavier because it has more mass compared to the pencil. Even though both objects experience the same gravitational force, the textbook contains more matter, making it harder for you to support its weight with your hand. On the other hand, the pencil has less mass, which means it requires less effort to hold it up.
Option A is incorrect because gripping the pencil with more strength does not affect the weight of the objects; it only determines how tightly you are gripping them.
Option B is incorrect because the force exerted by your hand repelling the textbook is negligible compared to the force of gravity acting on it.
Option D is incorrect because the strength of the Earth's gravitational pull is the same for both objects. The difference in weight is due to the mass.
