Explore gravitational forces, especially as they apply to circular and elliptical orbits.

1. With a big mass and a little one, simulate some orbits. What's necessary for there to be orbital motion? What kinds of orbital shapes can you make? What does the big mass do?

2. Try to make a circular orbit. Write down some observations about that process. Once you can do that pretty well, make another orbit at the same radius, but with a heavier planet how is this different (or not) from the previous orbit? What about circular orbits that are different distances from the big mass do they move faster/slower? ...are their orbital periods (time for an orbit) shorter or longer?

3. How does an object move differently in the different parts of an elliptical orbit?

4. How do different elliptical orbits compare in orbital period?

5. What happens if you make a big mass "orbit" another big mass that looks different from what you've seen before? When does that start happening what sorts of masses do this?

The Moon orbits Earth in a nearly circular orbit that lasts 27.32 days. 1) Determine the distance from the surface of the Moon to the surface of Earth in Mm. (Express your answer to three significant figures.) A planet orbits a star with an orbital radius of 1 AU. The star has a mass that is 1.60 times our own Sun's mass. 2) Determine the time for one revolution of the planet around the star in years. (Express your answer...

1)Two newly discovered planets follow circular orbits around a star in a distant part of the galaxy. The orbital speeds of the planets are determined to be 39.7 km/s and 53.7 km/s. The slower planet's orbital period is 8.02 years. (a) What is the mass of the star? (b) What is the orbital period of the faster planet, in years? 2)Two satellites are in circular orbits around the earth. The orbit for satellite A is at a height of 461...

Investigation 1: Electrostatic Forces In this investigation you will explore the nature of the electrostatic force between two electric charges. Using the simulation embedded below you will study the following: the dependence of the direction of the electrostatic force on the types of charges involved in the interaction the dependence of the magnitude of the force on the strength of the charges and the distance between them The simulation below shows two electric charges qA = 10x 10-4C (in red)...

1. Richard Florida describes “The Big Sort.” What forces propel this sorting? What are the implications of the Big Sort? 2. Brueckner describes a choice model of homelessness and policies to address homelessness. In particular, he says that well-meaning policies like minimum dwelling size can backfire. How can this happen? 3. Glaeser and Gyourko say that the mortgage interest deduction does not make good policy. Why, according to them, is this the case?
