Learn Farsi: کشش جاذبه در این سیاره قوی است. - The pull of gravity on this planet is strong.

It comes from the verb کشیدن (to pull or stretch). First, we take its present stem, which is کش. Then, we add the action noun suffix ـِش (-esh) to get کشش, meaning a pull or an attraction.

How do we link کشش and جاذبه together when speaking?

You need to use the ezafe vowel (an 'e' sound) to connect them. It is pronounced keshesh-e jazebeh. This links the two nouns together to mean the pull of gravity.

Why do we use در instead of a word for 'on' when talking about this planet?

In English, we say we are 'on' a planet, focusing on the surface. Farsi conceptualizes a planet more like a contained realm or location, similar to a country or a world. Therefore, در (in) is the natural preposition to use with سیاره (planet).

Does کشش only refer to a physical pull like gravity?

No, this action noun can also be abstract. Besides a physical pull, کشش is very commonly used to describe emotional or romantic attraction between people, or the magnetic appeal of a particular place or idea.
