1.) Go to http://www.fearofphysics.com > Visual Physics > Why Satellites Dont Fall2.) Observe what happens to the satellite when you input the following data:First SituationHeight = 500 milesSpeed = 0 mphAnimation Detail > highClick GOSecond SituationHeight = 500 milesSpeed = 100 mphThird SituationHeight = 500 milesSpeed = 25000 mph (don not input any commas)3.) Discuss your observations of motion for a satellite at a height of 500 miles above the earth, moving at a speed of: 0 mph 100 mph 25000 mph4.) For a satellite at a height of 500 miles, at what speed must the satellite be traveling to achieve a circular orbit? (A score of 100% will tell you that you have achieved a circular orbit).5.) Knowing that the Earth has a circumference of about 24,000 miles, how fast is someone standing on the equator traveling?6.) Describe the orbit of a geostationary satellite. How is a geostationary satellite useful?7.) Knowing that a geostationary satellite orbits above the Earths equator at a height of about 22,240 miles, calculate a geostationary satellites speed as it orbits around the Earth (be sure to show calculations). 8.) Describe how a satellite is able to maintain an orbit around the Earth without constant propulsion. Include what parameters need to be balanced for orbital motion to occur.9.) For a satellite already in perfect orbit around the Earth, what happens if: the satellites speed is reduced? the satellites mass is reduced?10.) Clearly describe (or draw) a force diagram of a satellite that is orbiting the Earth. Label all forces acting on the satellite with a single arrow (->), and indicate the direction and magnitude of the net force with a double arrow (=>). DO NOT draw any non-forces in the diagram.(The magnitude of the force is represented by the length of its arrow. Note that velocity and inertia is not a force.)
