Questions and Answers
What is the primary focus of physics within the realm of physical sciences?
Physics primarily focuses on the forces and energy that govern the motion of objects throughout the universe.
How does chemistry differ from physics in the context of physical sciences?
Chemistry focuses on the composition and structure of matter, while physics investigates forces and energy.
Describe the relationship between physics and chemistry within physical sciences.
Physics and chemistry are interrelated, as both study matter and energy; chemistry analyzes composition while physics examines forces affecting them.

Study Notes
Main Branches of Science
- Science is divided into three primary branches: Earth science, life science, and physical science.
Earth Science
- Focuses on Earth, its components, and its surroundings.
- Earth scientists investigate a variety of phenomena including:
- Effects of tsunamis on shorelines.
- Planetary orbits around the Sun.
- Formation of hurricanes.
- Subdivisions of Earth science include:
- Meteorology: Studies Earth's atmosphere, weather, and climate.
- Oceanography: Explores properties and processes of the oceans.
- Geology: Examines Earth’s interior and surface processes, often through the study of rocks and minerals to reconstruct historical geology.
- Astronomy: Investigates celestial objects beyond Earth's atmosphere, including those in the solar system and galaxies.
Life Science
- Concerned with all forms of life, from microorganisms to large animals, including humans.
- Life scientists study:
- Processes within living organisms.
- Interactions between different organisms in ecosystems.
- Example questions in life science include:
- Seasonal behaviors of trees and their leaf loss.
- Migratory navigation methods of birds.
- Body temperature regulation in mammals.
- Subdivisions include:
- Genetics: Focuses on DNA and hereditary information.
- Microbiology: Studies microorganisms like bacteria.
- Ecology: Looks at interactions between organisms and their environments.
- Zoology: Studies animal behavior and physiology.
Physical Science
- Merges the study of matter and energy, combining aspects of physics and chemistry.
- Physics: Examines forces and energy impacting the motion of objects, exploring from atomic to cosmic levels.
-
Chemistry: Investigates composition, structure, and properties of matter, including:
- The chemical reactions and their effects on matter.
- The relationships between a substance's composition and its physical characteristics.
- Chemistry's subdivisions allow a focus on various aspects such as reaction mechanisms and properties of materials.
