A satellite is in a circular orbit around the Earth. If its speed is increased, what will happen to its orbit?
  1. It will remain circular
  2. It will become elliptical
  3. It will crash into the Earth
  4. It will escape Earth's gravity

Questions & Step-by-Step Solutions

A satellite is in a circular orbit around the Earth. If its speed is increased, what will happen to its orbit?
  • Step 1: Understand that a satellite in a circular orbit moves at a constant speed around the Earth.
  • Step 2: Recognize that the speed of the satellite is balanced by the gravitational pull of the Earth.
  • Step 3: If the speed of the satellite is increased, it will no longer be balanced by gravity.
  • Step 4: The increase in speed will cause the satellite to move away from the circular path.
  • Step 5: As a result, the orbit will change from a circular shape to an elliptical shape.
  • Step 6: In an elliptical orbit, the satellite will have a point where it is closest to the Earth and a point where it is farthest.
  • Orbital Mechanics – Understanding how changes in speed affect the shape and characteristics of an orbit.
  • Types of Orbits – Differentiating between circular and elliptical orbits and the conditions that lead to each.
