Answer to Question 1

False

Answer to Question 2

Tidal forces affect orbital motion. For example, Earth rotates eastward, and friction with the ocean bed drags the tidal bulges slightly eastward out of a direct Earth-Moon line. These tidal bulges are massive, and their gravitational field pulls the Moon forward in its orbit. As a result, the Moon's orbit is growing larger by about 3.8 cm a year. Earth's gravitation exerts tidal forces on the Moon, and friction within the flexing rock has slowed the Moon's rotation to the point that it now keeps the same face toward Earth.
