More advanced force fields need to be written as custom code, either in python or as a pybullet C/C++ plugin.

Reading through the documentation, It doesn't seem like pybullet has friction except for joint friction. is this possible to do in pybullet?
how can I change the parameters to the spheres so they fall at different speeds?

Code: 

import pybullet as pimport randomp.connect(p.GUI)p.setGravity(0,0,-0.001)p.setRealTimeSimulation(0)objects = {}def create_snow():  for i in range(50):    objects[i] = p.createCollisionShape(p.GEOM_SPHERE)    p.changeVisualShape(objects[i],-1,rgbaColor=[random.random(),random.random(),0,1])    p.createMultiBody(random.randint(1,10),objects[i],-1,basePosition=[random.randint(-10,10),random.randint(-10,10),random.randint(2,5)])for i in range(1000000000):  p.stepSimulation()  if i % 100000 == 0:    create_snow()
