Newton's Law of Universal Gravitation
The force of gravity between two objects is determined by:
* Mass (m1 and m2): The larger the masses of the objects, the stronger the gravitational attraction.
* Distance (r): The closer the objects are, the stronger the gravitational attraction.
The Key Point:
While a more massive object exerts a stronger gravitational pull overall, the force of gravity is *mutual*. This means both objects are attracted to each other, even if one is much smaller.
Examples:
* Earth and a satellite: The Earth has a much larger mass than a satellite. The satellite orbits the Earth because the Earth's gravity pulls on it, but the satellite also exerts a tiny gravitational force on the Earth.
* A planet and a small asteroid: The planet's larger mass means its gravitational pull is stronger. The asteroid will be drawn towards the planet. However, the asteroid also exerts a gravitational force on the planet, just a much weaker one.
In Conclusion:
Even if one object has a much larger mass than the other, both objects experience a gravitational force towards each other. The more massive object exerts a stronger force, but the force is still mutual. This is why even small objects in space are influenced by the gravity of larger objects.
