Question 101: Gravitation

Question

Choose the incorrect statement from the following:

Accepted Answer

The linear speed of a planet revolving around the sun does not remain constant, as planets follow an elliptical orbit around the sun. According to Kepler's second law, the areal velocity of a planet remains constant, which means that the planet moves faster when it is closer to the sun (at perihelion) and slower when it is farther away (at aphelion).

Answer

When a body falls towards earth, the displacement of earth towards the body is negligible.

Answer

The speed of satellite in a given circular orbit remains constant.
