What is the formula for gravity?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The universal law of gravitation formula is: F = G(m₁m₂)/r²
Where:
- F = gravitational force between two objects
- G = gravitational constant (6.674 × 10⁻¹¹ N⋅m²/kg²)
- m₁ and m₂ = masses of the two objects
- r = distance between the centers of the two objects
For calculating weight on Earth's surface, we use the simpler formula: F = mg, where m is mass and g is the acceleration due to gravity (9.8 m/s²).
