Question

scientists have studied the orbits of different planets. venus has a very circular orbit, while mars has a more oval - shaped (elliptical) orbit. according to keplers laws, how does the orbital speed of these planets change as they travel around the sun? hint 1: remember keplers laws—planets move faster when they are closer to the sun and slower when they are farther away. hint 2: since venuss orbit is almost a circle, it stays about the same distance from the sun, so its speed doesnt change much. marss orbit is more oval, so its distance from the sun changes more, which means its speed changes more, too. (1 point) both planets always travel at exactly the same speed throughout their orbits mars changes speed more than venus as it travels around the sun venus changes speed a lot, while mars travels at a constant speed

Explanation:

According to Kepler's laws, planets move faster when closer to the Sun and slower when farther away. Venus has a near - circular orbit, staying at about the same distance from the Sun, so its speed doesn't change much. Mars has an elliptical orbit, with a greater change in distance from the Sun, thus a greater change in speed.

Answer:

Mars changes speed more than Venus as it travels around the Sun
