ASTRONOMY 101 SAMPLE FIRST EXAM
[1]
Kepler’s Law relating the period,p, of a planet to the radius
(semi-major axis), a, of its orbit is, using a constant k,
(a) p = k/a
(b) p2 = k a3
(c) p3 = k a2
(d) p = k/ a2
[2]
Kepler’s third law states that a planet in an elliptical orbit moves with a
velocity such that
(a) the planet moves slower as it approaches nearer the sun.
(b) the line between the Sun and the planet sweeps out equal areas in
equal times.
(c) it won’t need to stop for the comets going by.
