Universal Gravitation — Quiz

Question 6 • Earth and Space Science

Which statement best explains why gravity is considered a centripetal force in our solar system?

Answer
A
It directs force outward, away from the Sun.
B
It pushes planets forward along their orbital path.
C
It repels objects toward the edge of the solar system.
D
It pulls planets inward, keeping them on a curved path.

Explanation

A centripetal force points toward the center of an object's curved or circular path. The Sun's gravity pulls planets inward and continually changes the direction of their motion, keeping them in orbit. It does not push planets forward or outward, so “It pulls planets inward, keeping them on a curved path” is correct.
