* Gravity itself is a force. It's the force of attraction between any two objects with mass.

* There's no other force that specifically "affects gravity." Gravity is a fundamental force of nature. It's not something that's changed or influenced by other forces in the same way forces like friction or magnetism might interact.

However, we can talk about things that influence the strength of gravity:

* Mass: The more massive an object, the stronger its gravitational pull.

* Distance: The closer two objects are, the stronger the gravitational force between them.

In a nutshell: Gravity is a fundamental force, and it's not "affected" by other forces in the way we usually think about forces interacting.
