Question

in 3-5 sentences, explain how the shape of planetary orbits affects their orbital velocity. Include the proper law of planetary motion as part of your answer.​

Answer 1

The shape of orbit varies from oval to round. Accordingly the velocity also varies. We can explain it using Kepler's law of motion.

Explanation:

Orbit is a path around every object in space. Every object moves in an orbit and the shape of every orbit is different. This shape of orbit affects the orbital velocity.

Now velocity of a planet depends upon the distance of a particular planet from the sun. A planet will move fast if it comes closer to the sun but if on an orbit if goes away from the sun than it will move slow. This is supported by Kepler's law of motion.

If the orbit has circular shape than its distance from sun will remain same and so speed will not vary much but in case of oval shape will be close to the sun at one point and far away from the sun at other point so the speed will vary   lot.
