Gravity ஈர்ப்பு
A steady pull in one direction that bends every moving thing toward it.
See it in Chromatic fluid. Raise Gravity, then drag through the fluid and watch the colour sink.
In plain words
Gravity pulls everything the same way, all the time. A ball thrown sideways keeps its sideways speed but gains downward speed each moment. That is why its path bends into an arc. In a simulation, gravity is a small push added to every particle's velocity every step. Turn it up and things fall faster; turn it negative and they rise.
