Newton’s second law states that acceleration is inversely proportional to the mass of an object when subjected to a given force. Because the mass of the Earth is much greater than the mass of the Moon, the acceleration of the ...

Newton’s third law states that for every action, there is an equal and opposite reaction. Thus, when the Earth exerts a gravitational force on the Moon, the Moon exerts an equal and opposite gravitational force on the Earth.
The force of attraction of the Earth provides the centripetal force that keeps the moon in orbit around it.
The gravitational force of the Earth attracts a falling apple towards it.
The acceleration due to the Earth’s mass is much larger than the acceleration due to the apple’s mass, making the motion of the Earth practically imperceptible compared to the motion of the falling apple.
The centripetal force acts towards the center of the circular path, keeping the stone moving along the path.
The centripetal force causes the change in direction of the stone’s velocity.
The stone changes direction at every point along the circular path.
The stone moves in a circular path before the thread is released.
Although the Earth’s gravitational force attracts the moon, we do not see the moon falling towards the Earth because the moon’s orbital motion keeps it in a stable orbit around the Earth.
