Answers

The perception of weight is subjective and influenced by various factors, including the physical properties and dimensions of objects, as well as psychological factors. In this case, there are a few reasons why the textbook may feel heavier than the pencil:
1. Physical weight: The textbook is likely to be significantly heavier than the pencil due to its larger size, greater mass, and more volume. Since weight is the force exerted by gravity on mass, these physical properties contribute to the textbook's higher weight.
2. Surface area: The textbook covers a larger surface area compared to the pencil. When you hold the textbook, your hand exerts force over a larger area, which may distribute the weight more evenly and make it feel less concentrated compared to when holding a narrow pencil.
3. Hand positioning: Generally, when holding a textbook, you might use both hands and distribute the weight between them. This technique engages more muscles and joints, which can make the textbook feel weightier than a pencil held with just one hand.
4. Expectation and perception: Our mind plays a significant role in our perception of weight. Based on prior experiences and knowledge about the relative weights of textbooks and pencils, your brain may anticipate that the textbook would be heavier. This expectation, in turn, can influence the perception of weight and make the textbook seem subjectively heavier.
Ultimately, the textbook feels heavier due to a combination of objective physical properties and individual perception.
