Which subject area includes motion and energy?

• A. Physical science.
• B. Earth science.
• C. Life science.
• D. Environmental science.

Answer: (A)

Motion and energy belong in physical science because this area covers how objects move and how energy changes form and transfers. In physical science, students explore forces, motion—including speed, direction, and acceleration—and the different forms of energy (kinetic, potential) and how they convert from one form to another. This foundational focus helps explain everyday phenomena like a ball rolling, a swinging pendulum, or a light switch turning on a lamp. Earth science, by contrast, centers on Earth’s materials and processes—rocks, oceans, weather, and geologic activity. Life science examines living organisms, their structures, functions, growth, and reproduction. Environmental science looks at how living things interact with their surroundings and how human actions impact natural systems. While energy and matter appear in those areas, the core emphasis of motion and energy topics is best captured within physical science.
