Why doesn't rigidbody2D.AddForce(-5, 2); work?

because it only suppports vectors: https://docs.unity3d.com/Documentation/ScriptReference/Rigidbody2D.AddForce.html

rigidbody2D.AddForce(Vector2(-5, 2));

This is from the scripting reference for a regular rigidbody requiring Vector3 coordinates.

    function FixedUpdate () 
    {
         rigidbody.AddForce (0, 10, 0);
    }

I guess putting rigidbody2D before addforce doesn't let it know that you are working with Vector2.

No rigidbody.AddForce(0, 10, 0); is a convenience method if you for some reason not use Vector3 in your code. They apparently decided not to add this for 2D.
