PhysicsObjectFrictionMaterial Property

'Visual Only' is just the graphics. 'Load' will be available to load creators and be affected by gravity. 'Vehicle' is like a load but isn't transient and remains in the scene after a Reset. 'Deflector' is fixed in space and will deflect other objects. 'Sensor' is fixed in space but will fire scripts when other objects come into contact with it.
