Correct option is D
The correct answer is (d) Centripetal force.
· The centripetal force is the force that keeps the moon in its nearly circular orbit around the Earth. This force is provided by Earth’s gravitational pull, which continuously attracts the moon toward its center, preventing it from flying off in a straight line.
Information Booster:
· Mechanical force: Refers to forces related to physical mechanisms but is not responsible for celestial motion.
· Centrifugal force: A fictitious force that acts outward on a body moving in a circular path but does not explain the moon's orbit.
· Friction force: A force that opposes motion between two surfaces in contact, but it doesn't apply in space where the moon orbits the Earth.
