* Newton's Law of Universal Gravitation: This law states that every object in the universe attracts every other object with a force that is:

* Proportional to the product of their masses: The more massive the objects, the stronger the gravitational force.

* Inversely proportional to the square of the distance between their centers: The closer the objects, the stronger the gravitational force.

* Inertia: Objects resist changes in their motion. The more massive an object, the more inertia it has, making it harder to accelerate.

Putting it Together

When two objects attract each other, the object with less mass will experience a greater acceleration due to the gravitational force. This is because the force acting on it is the same (since gravity acts equally on both objects), but its inertia is less. Think of it like this: a smaller, lighter object is easier to push than a larger, heavier one.

Example:

Imagine a tiny asteroid and a large planet. Even though both attract each other gravitationally, the asteroid will move much more dramatically towards the planet because it has much less inertia. The planet will also move, but its movement will be practically unnoticeable due to its immense mass.
