Common mistakes

• Orbital motion, natural and artificial satellites common mistake 1

  Giving a vague answer instead of directly addressing: (Physics only) State that gravity provides the force that allows planets and satellites to maintain circular orbits..

  Fix itAnswer by clearly explaining how to (Physics only) State that gravity provides the force that allows planets and satellites to maintain circular orbits..

• Orbital motion, natural and artificial satellites common mistake 1

  Giving a vague answer instead of directly addressing: (Physics only) Explain that an object moving in a circular orbit is accelerating because its velocity is changing direction..

  Fix itAnswer by clearly explaining how to (Physics only) Explain that an object moving in a circular orbit is accelerating because its velocity is changing direction..

• Orbital motion, natural and artificial satellites common mistake 1

  Giving a vague answer instead of directly addressing: (Physics only) State that for a stable circular orbit the speed of the object is constant but its velocity changes..
