VPhysics

Vphysics is the physical simulation engine used by the Source Engine. VPhys simulated objects have physical characteristics (such as mass and buoyancy), a collision hull, and are simulated by the VPhysics Engine that gives them inertia, velocity, and applies forces from gravity and collisions.

This category of objects includes physics props, physically simulated NPCs (like scanners, manhacks, rollermines), func_physbox entities, items that can be picked up (like weapon_smg1 or item_healthkit), drivable vehicles, thrown (and pickupable) frag grenades, and combine AR2 energy balls.

Other categories include hull simulated (like players, living (non physics based) NPCs, in-flight RPGs and SMG grenades) and ray simulated (bullets).
