* Every object with mass has a gravitational pull. The more massive an object, the stronger its gravitational pull.
* Gravity attracts objects towards each other. This means that the force of gravity between two objects acts along the line connecting their centers of mass.
Examples:
* An apple falling to the Earth: The apple's gravitational pull is much weaker than the Earth's, so it falls towards the Earth's center.
* The Moon orbiting the Earth: The Moon is constantly being pulled towards the Earth's center by gravity, but its sideways motion keeps it in orbit.
* The Sun and planets: All the planets in our solar system are attracted to the Sun's center of mass.
Important Note: While gravity always acts towards the center of mass, the direction of the force itself can be described in various ways depending on the context, such as:
* Downward: We often refer to gravity as a downward force on Earth because we are standing on the surface, and the Earth's center of mass is below us.
* Towards another object: We can describe the gravitational force between two objects as acting towards each other.
