The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster th…

If you go out to look at the night sky tonight from central Iowa, the North Star (aka Polaris) is located near the North Celestial Pole at an altitude of approximately 42 degrees above the horizon. Why is that the case? What is the altitude of the celestial equator at its highest point as viewed from this location and how do we calculate that? Explain the myth behind one of the constellations located near North Celestial Pole and then explain the myth behind another constellation along the ecliptic plane.

1. Why were the main reasons why the idea that the Earth was at the center of the universe lasted so long? 2. Discuss in 2 paragraphs the observations made by Galileo that disproved Geocentrism. Which one do you think was the most important? 3. Write down a hypothesis and observational experiment to test one of Newton’s laws of motion. EXPLAIN YOUR REASONING! 4. One of the first exoplanets discovered orbits the star 51 Pegasi with a period of just 4.2 days. 51 Pegasi is very similar to the Sun. Use Kepler’s laws to find the distance (in astronomical units) between the planet (unofficially named Bellerophon) and its star. SHOW YOUR WORK! 5. How does halving the distance between two objects affect the gravitational force between them? 6. Suppose the Sun were somehow replaced by a star with five times as much mass. What would happen to the gravitational force between the Earth and the Sun? 7. How long would the Earth year last in this last case? (hint: Newton’s version of Kepler’s 3rd…

In the figure below, Planet X is moving in a perfectly circular orbit around its companion star.The time between each position shown is exactly one month: 1. Write down Kepler’s second Law of planetary motion.2. Does the planet obey Kepler’s second law? How do you know?3. If you carefully watched this planet during the entire orbit, would its speed be increasing, decreasing, orstaying the same? How do you know?
