Can someone explain Physics tab?

What does newtonian,Keyed,Boids and fluid physic ? Where i can use them

This is for particles, yes?

Quick rundown:

Newtonian: each particle flies along a velocity which is effected by gravity, and any force fields, and bounces off any objects set to collision.

Keyed: This is used for the particles moving between one formation (surface of one object) to another.

Boids: this simulates how birds fly, or how creatures move along a surfice - avoiding collisions but still wanting to be part of the group.

Fluid: the most complex and confusing… like Newtonian, but the particles clump together like they are a fluid with some surface tension.

Yes Thank you.
