Satellite — Speed Increase EffectHardQuestion 30729
Question
If a satellite's speed is increased at a point in its orbit, it moves to:
- AA lower orbit
- BA higher orbitCorrect
- CSame orbit, just faster
- DEscapes Earth's gravity always
Correct answer
A higher orbit
Explanation
Increasing speed gives more energy → less negative total energy → larger orbit radius. (Decreasing speed → lower orbit.) This is why rockets must slow down to de-orbit — counter-intuitive!
