A comet orbits the sun is highly elliptical orbit. Does a comet has a constant.
(i) Linear speed

Text Solution

Verified by Experts

According to law of conservation of angular momentum L = mvr = constant.
`:.` The comet moves faster when it is close the sun and moves slower when it is farther away from the sun.
The speed of the comet does not remain constant.
