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.

1. Geostationary satellites are further away from the Earth's surface. This means that a lower gravitational force of attraction is present between the satellite and the Earth. What kind of tangential speed is required to keep this satellite in orbit?

  • A high one because too low a tangential speed will cause the satellite to fall to the Earth's surface.
  • A low one because too high a tangential speed will cause the satellite to move away, into space.
  • A high one because too low a tangential speed will cause the satellite to move away, into space.
  • A low one because too high a tangential speed will cause the satellite to fall to the Earth's surface.

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

  • 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 faster it travels. The further away from the Earth's surface a satellite is, the slower it travels.
  • 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.
  • 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.

3. A comet's orbit is:

  • elliptical
  • square
  • circular
  • hexagonal

4. The forward motion preventing Earth's gravitational pull from making a satellite fall to its surface is called:

  • friction
  • centripetal force
  • tangential motion
  • momentum

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

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