Gravitation Science & Technology part-1 SSC class10 in Hindi (Circular motion and Centripetal Force)

J. Sir・2 minutes read

Gravitational force, discovered by Sir Isaac Newton, is crucial in keeping celestial bodies like the moon in orbit around larger objects like Earth. Newton's laws of motion and Kepler's contributions further explain how external forces and centripetal force affect the motion of objects in the universe.

Insights

  • Sir Isaac Newton discovered gravitational force by observing an apple falling, which keeps celestial bodies in orbit around larger objects like Earth.
  • Kepler's study of planetary motion and the importance of centripetal force in circular motion contributed significantly to scientific understanding before Newton's laws of motion explained how external forces impact object motion.
