  • Gravity and Distance: How Does Force Change with Distance?
    The force of gravity between two bodies is inversely proportional to the square of the distance between them. This means:

    * If you triple the distance, the force of gravity will decrease by a factor of nine.

    Here's why:

    * Newton's Law of Universal Gravitation: This law states that the force of gravity (F) between two objects is directly proportional to the product of their masses (m1 and m2) and inversely proportional to the square of the distance (r) between their centers:

    F = G * (m1 * m2) / r^2

    Where G is the gravitational constant.

    * Tripling the distance: If you triple the distance (r), the denominator of the equation becomes (3r)^2, which is equal to 9r^2. Since the force is inversely proportional to the square of the distance, the force of gravity becomes 1/9 of its original value.

    In conclusion: Tripling the distance between two bodies reduces the gravitational force between them to one-ninth of its original strength.
