This force is what keeps a satellite in orbit. (13) 4. A comet orbits the sun in an __________ loop, whereas the planets have almost circular orbits. (10) 8. One use of a low polar orbit is _______ the Earth's surface. (7) 10. Low polar orbiting satellites can be used to forecast this. (7) Down 2. The period of time taken for a satellite to make one complete orbit. The higher the position above the Earth, the longer it takes to make a complete orbit. (7) 3. One use for low polar orbiting satellites is for military use for ______. (6) 5. A universal force of attraction between masses. (7) 6. The use of geostationary satellites can be used for Global Positioning Systems (GPS), weather forecasting, satellite phone calls and satellite __________. (10) 7. The force that acts towards the centre of a circle that keeps an object moving in a circle, provided by gravity. (11) 9. Geostationary satellites are in much higher orbits (36000km), therefore the gravitational force on them is ______. They move slowly and have further to travel. (6)
