The planets move in perfect circle orbits. Planets are not always the same distance from the sun. Planets are not always the same distance from the sun. A planet moves slower when it is closest to the sun.
The correct answers are:
1. The planets move in elliptical orbits.
2. A planet moves faster when it is closest to the sun.
3. Planets are not always the same distance from the sun.
The three correct answers are:
1. The planets move in elliptical orbits.
2. A planet moves faster when it is closest to the sun.
3. Planets are not always the same distance from the sun.
The three correct answers that support how the shape of planetary orbits affects their orbital velocity are:
1. The planets move in elliptical orbits: This statement explains that the planets do not follow a perfectly circular path but rather an elliptical one. This shape affects their orbital velocity as they vary their distance from the sun during different points in their orbit, causing their velocity to change accordingly.
2. A planet moves faster when it is closest to the sun: This statement indicates that the orbital velocity of a planet increases when it is at its closest point to the sun. This is because the gravitational force from the sun is stronger at this point, resulting in a higher velocity.
3. Planets are not always the same distance from the sun: This statement emphasizes that the distance between the planets and the sun is not constant throughout their orbit. As the planets move in elliptical orbits, their distance from the sun changes, affecting their orbital velocity.
