Forward Dynamics Model
A model that predicts the next state given the current state and action. It is the basic form of dynamics modeling and is commonly used as the prediction component within a world model, supporting rollout of future states and planning based on predicted consequences of candidate actions.

The inverse dynamics model answers "what action should be taken from the current state to the goal state," in contrast to the forward dynamics model; in hierarchical planning it serves as the low-level controller that translates high-level subgoals into concrete actions.
