Sir Isaac Newton and the Law's of Motion

• Sir Isaac Newton


  English physicist and mathematician, considered one of the greatest scientists of his generation
• Sir Isaac Newton


  • Discovered the law of universal gravitation
  • Enunciated the laws of momentum in mechanics
  • Built the first reflecting microscope in optics
  • Shared credit with Gottfried Wilhelm Leibniz for developing differential and integral calculus
  • Formulated the empirical law of cooling and studied the speed of sound
• Law of universal gravitation


  Explains the attraction between every particle in the universe
• Law of universal gravitation


  Found to be consistent with the laws of planetary motion postulated by Johannes Kepler
• Law of universal gravitation


  Helped prove Nicolaus Copernicus's idea that the sun, and not Earth, is the center of the solar system
• Force that causes an apple to fall from a tree to the ground

  Same force that pulls the moon toward the center of Earth
• Same force


  Responsible for the movement of Earth and other planets around the sun
• Newton's laws of motion

  • Law of inertia (Newton's first law of motion)
  • Law of acceleration (Newton's second law of motion)
  • Law of interaction (Newton's third law of motion)
• Newton's work on the laws of motion is considered to be of great significance as these laws became the principles on which other theories on motion were based
