public Momentum.State createState(Point initialPosition,
                                  Point initialVelocity)
```
    Description copied from interface: Momentum
    
    Create a Momentum.State instance. The Momentum.State instance will be passed to Momentum.updateState(State) until the momentum is depleted.
    
    Specified by:
    
    createState in interface Momentum
    
    Parameters:
    
    initialPosition - the initial position
    
    initialVelocity - the initial velocity in pixels per millisecond
  - updateState
```
public boolean updateState(Momentum.State state)
```
    Description copied from interface: Momentum
    
    Update the state based on the specified Momentum.State. When no more momentum remains, this method should return false to stop future calls.
    
    The Momentum.State instance is created by a call to Momentum.createState(Point, Point), and the same instance if used for the duration of the momentum. This method should modify the existing state by calling Momentum.State.setPosition(Point) and/or Momentum.State.setVelocity(Point).
    
    Specified by:
    
    updateState in interface Momentum
    
    Parameters:
    
    state - the current state
    
    Returns:
    
    true to continue momentum, false if no momentum remains
