how to move object by python script while keep its physics and collision

Question

I am using python script to move an object (a ball) in a room, and it should be in the room, not going out. I have set the rigid body, when play it is ok, it can stop when hit the wall. but when controlled by script, it goes through the wall.

    ball = bpy.data.objects['ball']
    ball.select_set(True)
    bpy.ops.rigidbody.object_add()
    bpy.context.object.rigid_body.mass = 1
    ball.select_set(False)

    ball.location[0] = ball.location[0]+0.1  #this is in timer, repeat

how can I make it stop automatically when hit the wall? can I running python code control its movements when in playing?

Example scene for physics collision

Run the script to get the scene.

import bpy

# select and delete all object
if bpy.context.object:
    bpy.ops.object.mode_set(mode='OBJECT')
    bpy.ops.object.select_all(action = "SELECT")
    bpy.ops.object.delete(use_global=True, confirm=False)

unit_settings = bpy.context.scene.unit_settings
unit_settings.system            = 'METRIC'
unit_settings.scale_length      = 1
unit_settings.length_unit       = 'METERS'
unit_settings.mass_unit         = 'KILOGRAMS'
unit_settings.time_unit         = 'SECONDS'
bpy.context.scene.use_gravity   = True
bpy.context.scene.gravity[0]    = 0
bpy.context.scene.gravity[1]    = 0
bpy.context.scene.gravity[2]    = -9.81


bpy.ops.mesh.primitive_plane_add(size=5, enter_editmode=False, align='WORLD', location=(0, 0, 0), scale=(1, 1, 1))
bpy.context.object.name = "floor"
bpy.ops.rigidbody.object_add()
bpy.context.object.rigid_body.type = 'PASSIVE'
bpy.context.object.rigid_body.collision_shape = 'BOX'


bpy.ops.mesh.primitive_cube_add(size=5, enter_editmode=False, align='WORLD', location=(5, 0, 0), scale=(1, 1, 1))
bpy.context.object.name = "wall"
bpy.ops.rigidbody.object_add()
bpy.context.object.rigid_body.type = 'PASSIVE'
bpy.context.object.rigid_body.collision_shape = 'BOX'


bpy.ops.mesh.primitive_cube_add(size=0.2, enter_editmode=False, align='WORLD', location=(0, 0, 0.101), scale=(1, 1, 1))
bpy.ops.rigidbody.object_add()
bpy.context.object.rigid_body.type = 'ACTIVE'
bpy.context.object.rigid_body.collision_shape = 'BOX'
bpy.ops.rigidbody.mass_calculate(material='Iron', density=7874)


bpy.ops.object.empty_add(type='CIRCLE', align='WORLD', location=(-0.41, 0, 0), rotation=(0, 1.5708, 0), scale=(1, 1, 1))
bpy.context.object.name = "force"
bpy.ops.object.forcefield_toggle()
