Why is life on Earth possible?
1. Our planet is just the right distance away from the Sun for water to exist as a liquid. (Goldilocks Zone)
2. Our Atmosphere provides us with ...
-spreading heat from the Sun around our planet
-provides us with protection from meteorite impact burning them up
-protection from the harmful ultraviolet (U.V) rays from the Sun
The Earth's movement through space affects life on Earth. We experience day and night because of the Earth's axis movement known as rotation. It takes the Earth approximately 24 hours to rotate one time in which we experience day and night. The Earth's axis is an invisible line that intersects the Earth through both the North and South Pole.
The Earth moves along an eliptical path around the Sun. This is known as a orbit. One complete trip on this path is known as a revolution. It takes the Earth 365 1/4 days to complete its journey around the Sun. Every 4 years, we take the extra 1/4 days, combine them and add an extra day to the calendar called Leap Year (February 29)
Frictional force between two objects in contact that are rolling.
Frictional force between two objects in contact that are sliding
Frictional force between two objects in contact, one of which is a fluid (liquid or gas).
Frictional force between two objects in contact that are causing it to stay at rest (no movement).
Newton's First Law of Motion (The law of inertia)
An object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted upon by an unbalanced force
Newton's Second Law of Motion
Force equals mass times acceleration (F=ma)
Newton's Third Law of Motion
For every action there is an equal and opposite reaction

The thickness of the plastic in plastic bags is about 0.001 mm. How many wavelengths of red light is this?
The smallest feature visible through an Earth-based telescope has an angular diameter of about 1 arc second. If a canal on Mars was just visible when Mars was at its closest to Earth, how wide was the canal? (Hint: Use the small-angle formula.)
Is there more or less mass in the Milky Way's disk and halo than we can see? Explain your reasoning.
Suppose the Milky Way was a band of light extending only halfway around the sky (that is, in a semicircle). What, then, would you conclude about the Sun’s location in the Galaxy? Give your reasoning.
