Question

Explain the motion of moon around the earth.

Answer 1

• The motion of the moon around the earth is called revolution.
• The moon moves around the earth in a nearly circular path.
• Hence the motion of the moon is circular motion.
• The gravitation force of the earth acts on the moon and provides the necessary centripetal force.
• The centripetal force acts towards the center of the orbit that is towards the earth.
• The moon moves in almost a circular orbit and goes around the Earth in 27.3 days
