night
what two factors affect gravity?
mass and distance

What happens to gravitational pull as the mass of an object increases?
gravity increases
planet, galaxy, star, natural satellite, universe, asteroid

Large objects and small objects should fall at the same speed on Earth because of gravity, but why do smaller objects actually fall slower on Earth? (feather vs. bowling ball)
air resistance (air pushes up on a feather - unequal balance of air and gravity)
how many stars are in galaxies?
billions to trillions
What caused the Moon's craters and dark areas on the surface?
meteors/asteroids crashing into the surface and ancient volcanoes
What causes the Lunar Phases?
1. sunlights reflection off the Moon's surface
2. change in the Moon's position as it orbits Earth
Why does the moon appear red during a lunar eclipse?
sunlight bending in the atmosphere
What two factors keep objects in orbit?
gravity and inertia/momentum
What did the styrofoam ball, hand, and string represent in the planet orbit demonstration?
styrofoam ball (earth)
string (gravity)
hand (sun)
