 1. How do you describe different gravity environments? 2. What are the characteristics of projectile motion? 3. How are elliptical orbitals maintained? 4. What were some significant contributions Isaac Newton made to the description of motion?
 * 1) Does knowing how to use a scale on a map help you understand how to use scale to measure distances in the universe? How are they similar? How are they different?
 * Yes because if you know how to do it you can measure the distances. They are similar because you are calculating the distance to a scale. They are different because a map is way smaller than the universe.
 * 1) Vast distances in space are often measured in light-years. A light-year is the distance that light travels in one year, or about 6 trillion miles. Altair, a star in the constellation Aquila, is 16.6 light-years away, which means that the light we see now from that star left its surface 16 years and 219 days ago. Describe what was happening in the world when the light we are seeing from Altair first left that star. How far away is Altair in miles?
 * We are pretty much looking 16 years and 219 days back in time I wasn't born yet but my brother who is now 20 was 4 at the time. 98.36 trillion miles away from earth.
 * 1) Explain why it would be impossible for scientists to measure stellar distances that are accurate to within a few feet. Why is it not critical to attain such accuracy when dealing with astronomical distances?
 * We can't because they are to far away and they don't have solid surfaces also they move. Things change they move they get smaller and bigger.
