when you hold a textbook and a pencil, why does the textbook feel heavier than the pencil?
a. The textbook has less mass than the pencil.
b. Your hand repels the textbook with less force.
c. The textbook has a stronger attraction to earth.
d. You can grip the pencil with more strength.
c. The textbook has a stronger attraction to earth.
The weight of an object is determined by both its mass and the force of gravity acting on it. Since the mass of the textbook is greater than that of the pencil, it has more particles and therefore more gravitational force acting on it. As a result, the textbook feels heavier when held.
