Choose the incorrect statement from the following:

Question

G1 Physics · Accepted Answer

A planet moving in an elliptical orbit does not have constant linear speed. From conservation of angular momentum, it moves faster near perihelion and slower near aphelion. A satellite in a fixed circular orbit has constant speed, and the remaining statements are consistent with gravitational interaction. Therefore the statement 'the linear speed of a planet revolving around the Sun remains constant' is the incorrect one. Hence option A follows.
