Q:

What happens if a satellite changes its speed?

A:

Many satellites orbit the Earth at an altitude of around 400 km (250 miles), called Low Earth Orbit (LEO). In order for a satellite to stay in low earth orbit, it must be moving at approximately  28,000 km/h (17,500 mph). Changing the speed of a satellite has major effects on its orbital path.
