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. A comet's orbit is:
- square
- elliptical
- hexagonal
- circular
3. 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
4. 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?
- Friction
- Centripetal force
- Momentum
- Tangential motion
5. As a comet nears the Sun, the speed at which it travels in its orbit increases. This is because:
- as the comet nears the Sun, the gravitational force of attraction between the comet and the Sun is greater
- the size of the comet increases as it gets closer to the Sun
- as the comet nears the Sun, the gravitational force of attraction between the comet and the Sun is greater
- when the comet is further away from the Sun, the gravitational force of attraction between the comet and the Sun is greater
