Question

1. which of the following best describes an object’s weight? a. the amount of space an object takes up. b. the force exerted by gravity on an object’s mass. c. the amount of matter in an object, constant everywhere. d. the speed at which an object falls to earth.

Explanation:

• Option A: The amount of space an object takes up is volume, not weight.
• Option B: Weight is defined as the force exerted by gravity on an object's mass (using \( W = mg \), where \( W \) is weight, \( m \) is mass, and \( g \) is acceleration due to gravity).
• Option C: The amount of matter in an object (constant everywhere) is mass, not weight.
• Option D: The speed at which an object falls is related to acceleration due to gravity and air resistance, not weight.

Answer:

B. The force exerted by gravity on an object's mass.
