  1. Principle of Superposition of Gravitational Forces
    Statement:
    The principle of superposition states that the gravitational force between any two masses acts independently of the presence of other masses. The resultant gravitational force on a particle due to multiple masses is the vector sum of the individual forces exerted by each mass.

    Mathematical Representation:
    The net gravitational force Fᵣ on a particle can be expressed as:
    Fᵣ = F₁ + F₂ + F₃ + … Fₙ = Fᵢ
    Here, F₁, F₂, F₃ , … Fₙ are the individual gravitational forces exerted by masses m₁, m₂, m₃ ,… Fₙ on a particle of mass 𝑚. Each force follows the law of gravitation.
