What is the force with which a planets gravity pulls on something?

The force with which a planet's gravity pulls on an object is known as gravitational force, calculated using Newton's law of universal gravitation. This force depends on the masses of both the planet and the object, as well as the distance between their centers, described by the formula ( F = G \frac{m_1 m_2}{r^2} ), where ( F ) is the gravitational force, ( G ) is the gravitational constant, ( m_1 ) and ( m_2 ) are the masses, and ( r ) is the distance. On the surface of a planet, this force is commonly expressed as weight, which is the product of mass and gravitational acceleration (e.g., Earth's gravitational acceleration is approximately 9.81 m/s²).
