Newton's law of gravitation
F = Gm₁m₂/r²
Where: F = force (N), G = gravitational constant (N·m²/kg²), m₁ = mass 1 (kg), m₂ = mass 2 (kg), r = radius / distance (m)
Solved example
Given: G = 7, m_1 = 5, m_2 = 10, r = 4
Find: F (force (N))
- Formula: F = G·m₁·m₂/r²
- Substitute the values: F = 10·5·7/4²
- Result: F = 21.875 N
Answer: F = 21.875 N
