A static object does not move (and is not moved) and have no mass.
It is therefore not affected by gravity or other objects.
Dynamic objects collide with static objects.

Returns:

true if this CollisionObject is static

isKinematicObject

public final boolean isKinematicObject()

It is moved manually, and is therefore like static object it is not affected by gravity or other objects.
Dynamic objects collide with kinematic objects.

Returns:

true if this CollisionObject is static
