Mechanics studies motion and forces, thermodynamics concerns heat, optics concerns light, and vibrations and wave phenomena include radio waves.
Branches and their subjects include:
1. What does physics study?
2. A researcher investigates how electricity and magnetism are related. Which branch of physics best fits this work?
3. A student proposes that plants exposed to more light will grow taller, then plans to test the prediction. What is this proposed explanation or prediction called?
What does physics study?
Matter, energy, and their interactions.
What is a hypothesis?
An educated, testable explanation or prediction.
What factor is changed during an investigation?
