All entities or world objects in V1 requireing them have their Physics attached by default in Single Player Mode, so you need do nothing really unless you wish to change this or make adjustments to the Physics properties of an entity say for instance if you wished something to be heavier or lighter in weight. All default objects will have default settings applied which are optimised already differently for each object instance appropriate to the behaviour that object should have - so they are already correctly set up for you. Changing any properties of Physics are not recommended until you get used to it or are prepared to cahnge them back if necessary as the results could be unpredictable.
The exception being an MP mode Game which has little or no users control over Physics. Any Physics are applied or removed automatically in an MP game by FPSC and you will have no choice in the matter.
A video of how to set up Physics is not needed as you dont have to set it up. User friendly, click and play.......
