Final answer:
Gravity is a physical property associated with mass. It is the force of attraction between any two objects with mass, and its strength depends on the mass of the objects. On Earth, the gravitational force pulls objects towards the center of the planet, causing them to fall to the ground when dropped.
Step-by-step explanation:
Gravity is a physical property that is associated with mass. It is the force of attraction that exists between any two objects with mass. The strength of the gravitational interaction depends on the mass of the objects involved. The more mass there is, the stronger the gravitational force will be.
For example, on Earth, the gravitational force pulls objects towards the center of the planet. This is why objects fall to the ground when dropped. The mass of Earth is much greater than the mass of a person or any other object on its surface, which is why Earth's gravitational pull dominates our everyday experiences.
Throughout the universe, any objects with mass will attract each other due to gravity. Gravity never becomes zero as it quickly gets weaker with distance but continues to exist.
