5.4.2 Newton's law of gravitation

• What are the 3 Newton’s law of gravitational (universal law of gravitational)

  • Each object has its own field. Interactions give rise to forces between the objects.
  • The force is proportional to the product of the masses. F ∝ M m .
  • And inversely proportional to the square of the separation distance. F ∝ 1/r^2
• Newton’s law of gravitation: the force between two point masses is proportional to the product of the masses and inversely proportional to the square of the separation between them.
