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?
The period of the Moon's orbit is 27.0 days. The radius of the Moon's orbit is 3.8 ×1083.8\ \times10^83.8 ×108 m. The period of a geostationary satellite is 1 day. What is the radius of the geostationary satellite's orbit.
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.
The period of a satellite in a circular orbit of radius R is T. The period of another satellite in circular orbit of radius 4R is
Which of the following shows correctly the relationship between the period of orbit, T and radius of orbit, r, of a planet?
Kepler’s 3rd law states the square of the orbital period is proportional to the cube of the orbital radius. (T2=r3)If a planet's orbital radius is doubled, what happens to the length of a year on that planet?
A kine drawn from a planet to the Sun always sweeps over equal areas in equal intervals of time When the planet moves further from the sun, the planet will move
