The law of areas explains why a planet moves slower when it is:
AFarther out
BNearer in
CAt the focus
DAt the centre
Answer & Solution
Correct answer: A. Farther out
1. Sweeping equal areas takes a longer arc when close in.
2. Farther out, a shorter arc covers the same area.
3. So the planet moves slower when farther from the sun.
