Gravitation questions

w31ha0 SG

1) The total energy of an object in orbit is the sum of kinetic energy and potential energy. If the total energy decrease, does it become more or less negative?
2) Why does a person in a satelite feel weightless although the g field strength is not zero?
3)What does the value of the gradient of the graph (lg (g-field strength) against lg r(distance)) represent?
4) Why must a geostationary satelite be above the equator?
5)Why is the value of g different at the equator and at the poles?
6)What are the advantages of low polar orbits and geostationary orbits

thx =)

Hi,

the answers to these questions are pretty standard and should be present in your school's notes or commercial notes. So there's no point for me to regurgitate everything from the notes.

Do check your notes. Thanks :)
