ISP Exam Two information Review: Conservation of Energy : Energy can be transferred from one object to another or transformed from one type to another, but the total amount of energy is always conserved. Conservation of Angular Momentum: An object’s angular momentum cannot change unless it transfers angular momentum to another object. Because angular momentum depends on the product of mass, velocity, and radius, a spinning object must spin faster as it shrinks in size and an orbiting object must more faster when its orbital distance is smaller. Gravity: every mass in the universe attracts every other mass through the force called gravity. The strength of gravity between the two objects depends on the product of the masses divided by the square of the distance between them. Chapter 6 Order of the planets from closest to farthest from the Sun? SUN-- Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune-- Orbit- All the planets orbit counterclockwise around the Sun. THE SUN: Contains more than 99.9% of the total mass in our solar system Largest and brightest object in our solar system Hot sea of hydrogen and helium gas- 98% Gaseous throughout-higher temps as you go deeper Sun’s source of energy lies in the core where the temperatures and pressure are so high that the Sun is a nuclear fusion power plant. Radius is 108R Earth It is a star Mercury: Hot rock At any given time, about half the planet is colder than Antarctica. Its surface is heavily cratered Has essentially no atmosphere Venus: Cloudy planet Surface is hotter and smoother than Mercury’s Another rock Planet that has the highest average surface temperature. Earth The water planet The double planet Two rocks Mars A frozen planet Also a rock We have landed spacecraft on its surface It is considered part of our inner solar system It is frozen today, but once had flowing water Asteroid Belt Lots more rocks Jupiter A gaseous planet, H and He

NOT A ROCK Jupiter’s Moons (Galilean Moons) Four largest discovered by Galileo Io, Europa, Ganymede, and Callisto Saturn: Giant and gaseous like Jupiter Rings are made of ice chunks Cassini mission: the orbiter that orbits Saturn and a probe that descended into the atmosphere of Titan. Uranus: Tilted planet Giant and gaseous Has many moons Pluto: dirty ball of ice Features of our solar system that provide clues of how it formed: Patterns of motion among large bodies: Sun, planets, and large moons generally orbit and rotate in a very organized way. Two major types of planets: Small, rocky planets are close together and close to the sun Large, gas-rich planets that are farther apart and way from the sun Terrestrial Planets: planets that are mostly rock and metal are small Inner solar system Relatively small and dense with rocky surface and abundance of metals Mercury, Venus, Earth, and Mars Made almost entirely out of elements heavier than hydrogen and helium according to modern science these elements were produced by stars that lived and died before our
