  2. We do not see the moon falling towards the Earth despite gravitational attraction because its orbital motion creates a balance. The moon's forward velocity keeps it in a stable orbit, preventing it from crashing into the Earth.

  3. Newton explained the moon's orbit around the Earth by suggesting that gravitational force pulls the moon towards the Earth, but its forward motion creates a continuous free fall, resulting in a stable orbit rather than a direct collision.
