What to Focus On
- Physics studies nature and natural phenomena.
- Science is systematic knowledge built from observation and testing.
- The scientific method has four steps: observation, hypothesis, testing, modification.
- Physics is divided into major branches for systematic study.
- The major branches include mechanics, thermodynamics, electrodynamics, optics and relativity, atomic and nuclear physics, electronics and communication, astrophysics, and computer science.
- Different branches often use the same basic principles in different situations.
- Mechanical energy is conserved for motion under a conservative force.
- Total energy of an isolated system is always conserved.
- Einstein unified mass conservation and energy conservation.
Common Mistakes to Avoid
Physics is only about machines, motion, and formulas.
Scientific method means simply doing an experiment once and writing the result.
A law of physics is fixed forever and can never be changed.
