ppefmh	Ed	Garstin	3/4	The diagram shows a satellite orbiting the Earth. The arrow shows the direction that the satellite is moving. The satellite orbits the Earth once every 24 hours.		Polar satellites Gravitational satellites Geostationary satellites	We can see that in six hours, the satellite has completed 1/4 of its orbit around the Earth. This means that its total orbit will take twenty four hours. We can see that in six hours, the satellite has completed 1/2 of its orbit around the Earth. This means that its total orbit will take twenty four hours. We can see that in six hours, the satellite has completed 1/12 of its orbit around the Earth. This means that its total orbit will take twenty four hours.	We can see that the direction that the satellite points is constantly changing, even though its speed remains the same. Because the direction is changing, the velocity of the satellite is also changing. We can see that the direction that the satellite points is static, even though its speed remains the same. Because the direction is static, the velocity of the satellite is also changing. We can see that the direction that the satellite points is constantly changing, even though its speed remains the same. Because the direction is changing, the velocity of the satellite is constant.		When a satellite increases in speed, it requires a greater force of gravity to prevent the satellite flying off into space. By moving closer to the Earth, this increases the force of gravity and keeps the satellite in a stable orbit. When a satellite increases in speed, it requires a less force of gravity to prevent the satellite flying off into space. By moving closer to the Earth, this decreases the force of gravity and keeps the satellite in a stable orbit. When a satellite decreases in speed, it requires a greater force of gravity to prevent the satellite flying off into space. By moving further from the Earth, this increases the force of gravity and keeps the satellite in a stable orbit.	75%
