Who discovered the inverse square law for gravity ?

Correct answer: C. Newtons

  • A. Einstein
  • B. Galileo
  • C. Newtons
  • D. Plank

Explanation

Newton formulated the inverse-square law of gravitation, F = Gm1m2/r2, which states that gravitational force decreases with the square of the separation r. Therefore, doubling the distance reduces the force to one-fourth. Students may choose Einstein because of general relativity, but Newton discovered the classical inverse-square law.

About Newton's Laws of Motion

Newton’s laws explain inertia, the relation between net force and acceleration, and action-reaction pairs. Questions involve free-body diagrams, balanced and unbalanced forces, F = ma, force as the rate of change of momentum, and identifying genuine third-law pairs, which act on different bodies.
