Satellites, Centripetal Force and Tangential Motion

A GCSE-level quiz relating to the Satellites section in the OCR Gateway Physics P5 module. It asks about the different types of orbit an artificial satellite can have around Earth, the orbital path of each type of satellite and how each satellite's distance from Earth affects its orbit.

2. Satellites in low polar orbit pass over the poles and orbit the Earth 100-200km from its surface. How long is their orbital period?

  • 90 minutes
  • 60 minutes
  • 120 minutes
  • 30 minutes

3. Gravity provides something, without which objects such as planets would not orbit their stars and instead move away at a tangent. What is it that gravity provides that prevents this from happening?

  • Centripetal force
  • Friction
  • Tangential motion
  • Momentum

4. A comet's orbit is:

  • square
  • elliptical
  • hexagonal
  • circular

5. When a satellite is orbiting the Earth, how does its distance from the Earth affect the speed of its orbit?

  • The closer to the Earth's surface a satellite is, the faster it travels. The further away from the Earth's surface a satellite is, the faster it travels.
  • The closer to the Earth's surface a satellite is, the faster it travels. The further away from the Earth's surface a satellite is, the slower it travels.
  • The distance from the Earth's surface to a satellite doesn't affect the speed of the satellite's orbit.
  • The closer to the Earth's surface a satellite is, the slower it travels. The further away from the Earth's surface a satellite is, the faster it travels.
