  1. The speed at which any planet moves through space is constantly changing. In a perfectly circular orbit, the orbital radius of the planet would be constant and therefore so would be its observed angular velocity. In elliptical orbits, the velocity varies. In elliptical orbits, the orbital radius of the satellite will vary and therefore so will its velocity. The planet travels "faster" when closer to the Sun, then "slower" at a more distant radius. According to Newton's 2nd Law, what is the underlying force behind this change in velocity?

  2. Earth's orbital radius is 1.5 x 10^11 m and it orbits the Sun in 1 year. If Mercury's orbital radius is 5.79 x 10^10 m, calculate the time taken for it to orbit the Sun.Radius orbit Bumi ialah 1.5 x 10^11 m dan Bumi mengelilingi Matahari dalam tempoh 1 tahun. Jika radius orbit Utarid ialah 5.79 x 10^10 m, kira masa yang diambil untuk mengorbit Matahari.
