Question and answer
Which of the following statements about planetary motion is false? A. Each planet would move in a straight line without the Sun's gravitational pull. B. Each planet has a period of revolution
and a period of rotation. C. Each planet moves in a circular orbit around the Sun. D. A planet's speed changes as it orbits the Sun.
The FALSE statement about Planetary Motion is: Each planet would move in a straight line without the Sun's gravitational pull. ***The sun's gravitational force is very strong. [ If it were not, a planet would move in a straight line out into space forever. The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving
in an orbit around the sun. ]
