Physics Exam Notes

Motion and Early Physics

  • August: Introduction to motion.
  • Physics starts with observable phenomena (big objects).
  • Galileo: Studied falling objects from the Leaning Tower of Pisa.
    • Determined that mass does not affect the rate of falling.
    • Studied projectiles.
  • Newton: Formalized the laws of motion.

Developments Over Time

  • Post-Newton: Slow progress in the 1700s and 1800s.
  • Industrial Revolution: Understanding heat as a form of energy (not matter or a fluid).
    • Revolutionary for energy and energy transformations.
  • Electricity and magnetism: Integrated into physics.
  • Light: Debate over whether light is a particle or a wave.
    • Young's double-slit experiment (early 1800s): Proof that light is a wave.
    • Led to more questions and discoveries.

Late 1800s: A Perceived Dead End

  • Physicists thought they had answered most major questions.
  • Physics was considered a
