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.
When Earth orbits around the sun, it slows down when it is close to the sun. It speeds up its orbit when it is further from the sun. This is because the sun's gravity is stronger when you are closer to it.
Planets orbit the sun in a shape called an ellipse.
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.
The place where a planet is farthest away from the Sun in its orbit around the Sun is called the
The farther away a planet is from the sun, the _______ it takes it to orbit the sun once.
In order for a satellite to orbit in a higher orbit, what must be true about its speed
An orbit with the eccentricity of 0.9 would have more of a(n) __________ shaped orbit.
Which of the following shows correctly the relationship between the period of orbit, T and radius of orbit, r, of a planet?
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
Kepler’s first law states that planets travel in a(n) orbit.
What is it called when earth reaches the point in orbit when it is farthest from the sun?
When a planet orbits the Sun, one of the foci of the elliptical orbit is
The angle between the orbital plane of the solar system and the actual orbit of an object around the sun
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?
How can the position of the sun in earth's orbit be described?
Earth and the other planets closest to the Sun are made mostly of _______
Kepler's first law states that the orbits of the planets are oval in shape or
Planets travel faster when they are closer to the sun.
Planets travel around the sun in __ orbits
