In Jain Dharma, gati does not mean gravity.

Gati means the state or realm of birth/existence where a soul goes according to its karma. There are four gatis:

1. Naraki gati — hellish existence
2. Tiryanch gati — animal/plant existence
3. Manushya gati — human existence
4. Deva gati — heavenly existence

So, gati = destination/state of soul, not a physical force like gravity.

If you want, I can also explain the Jain meaning of gati, dravya, and karma in simple words.
