Once a satellite is accelerated into an orbit above the atmosphere, it can "coast" because there is almost no friction in the airless vacuum to slow it down. Any contact with air particles will slow down the satellite, and might eventually cause it to lose orbital speed and re-enter the atmosphere. (To be in "orbit" around the Earth, a satellite must be going fast enough to 'fall past' or 'fall around' the Earth's curved surface, as gravity tries to pull it down again.)
What else can I help you with?
Do satellites have an engines?
satellite has no engine
In the movie Independence Day why do the aliens use and need Earth's satellites?
The aliens need to use earth's satellites so that they can coordinate their invasion efforts.
Do you need a susbscrption to use a gps?
No. GPS Satellites are free to receive.
Do you need to be connected to the internet to use the GPS?
No as GPS is obtained from satellites.
What happen if you use spark plugs in diesel engines?
Nothing. That is, literally nothing. It doesn't work. Diesel engines don't use spark plugs, because they don't need them.
What type of plug do diesel engines need?
None. Diesels don't use plugs.
How many satellites needed to get a position?
Typically, three satellites are needed to determine a 2D position (latitude and longitude), while four satellites are needed to determine a 3D position (latitude, longitude, and altitude) using GPS technology.
What has happened to the satellites after 1957?
More satellites have been launched for different use of technology
How do you find a s?
Need to know what year and engine size. Some engines do not use a distributor.
Does nascar use inline 6 engines?
No, they use V8 engines.
Do blimps need engines to fly?
no, but you need engines to control the airship (AKA blimp)
How do satellites get their energy?
Satellites typically use solar panels to convert sunlight into electricity. This electricity is used to power the satellite's systems and keep it running while in space. Some satellites may also have batteries for storing energy to use when not exposed to sunlight.
