Questions and Answers

What is the formula to calculate gravitational force between two objects?

  • F = (m * v^2) / r
  • F = (G * m1 * m2) / r^2 (correct)
  • F = G * (m1 + m2) / r
  • F = m * g

    • What did Isaac Newton's law of universal gravitation state?

  • Every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers (correct)
  • Gravitational force is directly proportional to the distance between two objects
  • Gravitational force depends only on the mass of the objects
  • Gravitational force is inversely proportional to the product of their masses

    • What is the SI unit of gravitational force?

  • Joule
  • Newton (correct)
