Answer:
The universal law of gravitation, formulated by Sir Isaac Newton, states that every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This law is expressed by the equation:
\[ F = \frac{G \cdot m_1 \cdot m_2}{r^2} \]
where:
- \( F \) is the gravitational force between the masses,
- \( G \) is the gravitational constant,
- \( m_1 \) and \( m_2 \) are the masses of the two objects, and
- \( r \) is the distance between their centers.
Explanation:
every object in the universe attracts every other object the force of attraction between two object is proportional to the product of their masses and inversely proportional to the square of their distance between them
