Questions & Step-by-Step Solutions

What is the effect of increasing the mass of a satellite on its orbital radius?
  • Step 1: Understand that a satellite orbits a planet due to gravity.
  • Step 2: Know that the gravitational force depends on the mass of the planet (like Earth) and the distance between the planet and the satellite.
  • Step 3: Realize that the mass of the satellite itself does not change the gravitational force acting on it in a way that affects its orbit.
  • Step 4: Remember that the orbital radius is mainly determined by the mass of the Earth and the speed at which the satellite travels.
  • Step 5: Conclude that increasing the mass of the satellite does not change its orbital radius.
