| PhysicsBody |
A body is contained within a world and has 3 degrees-of-freedom, two for position and one for rotation.
A body can have forces, torques and impulses applied to it.
A body has three distinct types:
Static: This type of body does not move under simulation and behaves as if it has infinite mass, essentially an immovable object. Static bodies never interact with other Static or Kinematic bodies.Dynamic: This type of body is fully simulated and moves according to forces and torques applied to its linear/angular velocities. It can interact with all other body types. It always has finite, non-zero mass.Kinematic: This type of body moves under simulation and moves according to its linear/angular velocities and never uses forces or torques. It only interacts with Dynamic body types. It behaves as if it has infinite mass. A body is automatically destroyed when the world it is in is destroyed. A body cannot exist outside a world.

| PhysicsBodyDefinition |
A PhysicsBody definition used to specify important initial properties.
|
| PhysicsCallbacks |
Callback targets for object events.
|
| PhysicsChain |
A dedicated shape that produces a chain of shapes connected together to produce a continuous surface.
Chain shapes provide a smooth, continuous surface that will not produce "ghost" collisions.
A PhysicsChain is automatically destroyed when the body it is in is destroyed. A PhysicsChain cannot exist unattached from a body.
This will produce shapes of type PhysicsShape.ShapeType.ChainSegment.
Chains are one-sided.A chain has no mass and should be used on static bodies.A chain can have a counter-clockwise winding order (normal points right of segment direction).A chain is either a loop or open.A chain must have at least 4 points.The distance between any two points must be greater than PhysicsWorld.linearSlop.A chain should not self intersect (this is not validated).An open chain has no collision on the first and final edge.You may overlap two open chains on their first three and/or last three points to get smooth collision. |

|
| PhysicsJobOptions2D | A set of options that control how physics operates when using the job system to multithread the physics simulation. |

A joint is used to constrain bodies to the world or to each other in various ways.
A joint is automatically destroyed when either body it is attached to is destroyed. A joint cannot exist unattached from a body.
|
| PhysicsLayers |
This provides a common method to retrieving layer information.
If a PhysicsLowLevelSettings2D asset is assigned then the full layers (PhysicsLowLevelSettings2D.physicsLayerNames) will be used if PhysicsLowLevelSettings2D.useFullLayers is also active.
If no PhysicsLowLevelSettings2D asset is assigned then the global layers (See UnityEngine.LayerMask) will be used.

|
| PhysicsRelativeJoint |
A joint constraint used to control the relative movement two bodies while still being responsive to collisions.

| PhysicsShape |
A shape is attached to a body and defines an area to which two distinct types of behaviour are handled:
Collision: Contacts between shapes produce a collision response on their respective bodies, assuming their body type is Dynamic.Trigger: Contacts between shapes do not produce a collision response, only the fact that they're overlapping is reported. An unlimited number of shapes can be attached to a single body, known as a compound body.
A shape is automatically destroyed when the body it is attached to is destroyed. A shape cannot exist unattached from a body.
