NetLogo/Physics Example: Import a world with friction, gravity, wrapping, linear impulses and angular impulses. The world can contain moving shapes, static shapes, joints and targets, any of which can be represented by turtles.

Objects in a Box2D Physics World

	A line has two endpoints and is a member of a body. A line has friction, density and restitution. A line can be defined with an absolute position, or with a position relative to a body.
	A circle has a center and a radius and is a member of a body. A circle has friction, density and restitution. A circle can be defined with an absolute position, or with a position relative to a body.
	A polygon has vertices and is a member of a body. A polygon has friction, density and restitution. A polygon can be defined with an absolute position, or with a position relative to a body.
	A body can be comprised of shapes such as lines, circles and polygons. A body can be rotated around it's center. A body has linear and angular velocity. A body is defined with an absolute position. Bodies can be dynamic (move and collide) or be static (only collide) or be a ghosts (only move).
	A target is a location on a body, to which forces can be applied.
