Question

select the correct answer. which of the following best describes physical science? a. the study of motion b. the study of matter and energy c. the study of earths structure and processes d. the study of reactions e. the study of living things

Explanation:

• Option A: The study of motion is part of physics (a physical science), but it's too narrow to define physical science as a whole.
• Option B: Physical science (including physics, chemistry, etc.) focuses on the study of matter and energy, their properties, interactions, etc. This is a comprehensive description.
• Option C: The study of Earth's structure and processes is Earth science, a part of natural science but not the core of physical science.
• Option D: The study of reactions is mainly chemistry, but again, too narrow for physical science.
• Option E: The study of living things is biology, a life science, not physical science.

Answer:

B. the study of matter and energy
