Study Notes
Ancient Astronomy
- Aristotle described nature as dynamic, powerful, and teleological.
- Eudoxus described the motions of the heavens in terms of concentric spherical shells with the Earth at the center.
- Plato explained the irregular motions of the planets by proposing that the planetary spheres rotate to "save the appearances" of celestial bodies.
Renaissance Astronomy
- Tycho Brahe measured the relative distances from the Earth to the Sun and the Moon.
- Tycho Brahe published the Tychonic System, which represented the rotation of objects around the Earth and the Sun.
- According to Tycho Brahe's model, the objects that rotate around the Earth are the Moon, Sun, and planets, while the fixed stars rotate around the Sun.
Planetary Motions
- Galileo discovered the phases of Venus and the mountains of the moon.
- Galileo discovered four moons of Jupiter.
Laws of Motion
- Aristotle described the natural motion of the elements as being towards their natural places.
- Aristotle's Law of Motion is F = ma (Force equals mass times acceleration).
- According to Aristotle, the two classes of motion are natural and violent motions.
Modern Physics
- The study of motion or movement and what produces and affects it is called dynamics.
- Celestial bodies are objects in the universe, such as planets, stars, and galaxies.
Energy
- Kinetic energy is often called "energy in motion".
- When work is done against gravity, potential energy is changed.
- When work is done against friction, heat is produced.
- Factors that can contribute to the potential energy possessed by a body include gravity, elasticity, and electric charges.
- Potential energy is the energy an object has due to its position or state.
Light and Color
- The three primary colors that the human eyes' color-sensitive cells called cones respond to are red, green, and blue.
- The optical phenomenon that allows us to see objects through reflection in flat mirrors is called reflection.
- When a ray of light travels through a transparent medium and encounters a boundary leading into another transparent medium, it refracts.
- The nature of light according to the Wave Model is that light is a wave.
Electricity
- The unit of electrical charge is named after a famous scientist, the coulomb.
- Alessandro Volta extended Ohm's Law to deal with situations where more than one resistor was connected to more than one battery.
- James Clerk Maxwell translated Faraday's theories into mathematical expressions and has an electromagnetic unit named in his honor.
- James Clerk Maxwell demonstrated that electric and magnetic fields travel through space as waves at the speed of light.
