Study Notes
- Alteration, natural, and violent types of changes are exemplified by boiling water, earthquakes, and explosions, respectively.
- The precession of the equinoxes causes a gradual shift in the position of the equinoxes over time, altering the constellations associated with different seasons.
- Ancient Greeks did not attribute Earth's sphericity to religious or mythical reasoning.
- "Saving the appearances" refers to creating models that explain observed celestial motions from Earth, even if the underlying assumptions are incorrect.
- The Eudoxian model proposed by Eudoxus of Cnidus featured Earth at the center of 27 celestial spheres.
- The moons of Jupiter were a phenomenon first observed in ancient astronomy with the use of a telescope by Galileo.
- A geocentric model, which places Earth at the center, is not a heliocentric model of the universe.
- Johannes Kepler demonstrated that planets move in elliptical orbits.
- Johannes Kepler was Tycho Brahe's most famous student.
- Kepler's Third Law dictates that a planet's orbital period increases with its distance from the Sun.
- Using Kepler's Third Law to determine a planet’s orbital period at 4 AU the answer is 8 years.
- Using Kepler's Third Law, Jupiter's estimated orbital period is approximately 11.8 years.
- Aristotle believed that objects fall at a speed directly proportional to their weight.
- Galileo argued that objects in motion remain in motion unless acted upon by an external force, differing from Aristotle's view.
- Galileo demonstrated projectile motion as a combination of independent horizontal and vertical motions.
- Vertical and horizontal motions in projectile motion are independent; horizontal motion is constant, while vertical motion is affected by gravity.
- Galileo described projectile motion as following a parabolic path due to constant horizontal motion and accelerated vertical motion.
- An arrow shot as a projectile will follow a parabolic trajectory.
- According to Aristotle, Bryan's kite experienced violent motion because its motion was not due to its nature.
- In a vacuum, all objects fall at the same rate regardless of mass.
- Doubling the force and quadrupling the mass on an object results in halving its acceleration.
- The acceleration of free-falling objects is affected by location because gravitational acceleration varies.
- A satellite at an altitude equal to Earth's diameter experiences a force of 1/9 F.
- Newton’s first law applies to objects at rest or moving with constant velocity.
- Newton's Third Law explains why your foot hurts when you kick a wall due to equal and opposite reaction.
- Neglecting air resistance, all objects will reach the ground at the same time, regardless of mass or shape.
- An object's weight decreases as it moves farther from Earth due to a weakening gravitational force.
- Newton's Third Law (Law of Interaction) is connected to the conservation of momentum.
- The law of conservation of energy states that the total amount of energy in the universe is constant.
- When two cars collide with equal but opposite forces, their accelerations are not necessarily equal because of differences in mass.
