What to Focus On

  • Gravitational force exists between all objects in the universe
  • The force is always attractive in nature
  • It becomes noticeable only with very large masses

  • Force is proportional to product of masses (m₁ × m₂)
  • Force is inversely proportional to square of distance (1/r²)
  • G is universal gravitational constant = 6.67 × 10⁻¹¹ Nm²kg⁻²

  • g = 9.8 m/s² near Earth's surface (average value)
  • All objects fall with same acceleration (ignoring air resistance)
  • g is independent of the mass of falling object

Common Mistakes to Avoid

Heavier objects fall faster than lighter objects

Weight and mass are the same thing

Gravitational force only acts downward

Memory Tips

Newton's Law of Universal Gravitation Formula: F = G(m₁m₂)/r²

Value of Universal Gravitational Constant G = 6.67 × 10⁻¹¹ Nm²kg⁻²

Acceleration due to gravity g = 9.8 m/s²

Weight = Mass × g (W = mg)
