How do I do rb.AddForce but in 2D?

I am making a 2D game where you control a shield and you have to block falling obstacles from reaching base. I know that to move something you use rb.addforce. However, when I do the same for 2D it doesn’t work. I imagine that instead of using a Vector3 you use a Vector2, but it gives me these 2 errors: Assets\Movement.cs(16,25): error CS1503: Argument 1: cannot convert from 'float' to 'UnityEngine.Vector2' and this one: Assets\Movement.cs(16,25): error CS1503: Argument 1: cannot convert from 'float' to 'UnityEngine.Vector2' for each time I write the line. Here is my full code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Movement : MonoBehaviour
{
    public Rigidbody2D rb;
    public Collider2D collider;

    public float moveSpeed = 0.1f;

    private void Update() 
    {
        if (Input.GetKey("w"))
        {
            rb.AddForce(0f, moveSpeed);
            Debug.Log("w");
        }

        if (Input.GetKey("s"))
        {
            rb.AddForce(0f, moveSpeed);
            Debug.Log("s");
        }
    }
}

Rigidbody2D.AddForce takes two arguments, the first one is a Vector2 and the second is the type of force that will be used AddForce(Vector2 force, ForceMode2D mode = ForceMode2D.Force);0

In order to use this method you need to provide a Vector2 for the direction of the force and multiply that by your moveSpeed (Which I think should be called moveForce instead).

rb2D.AddForce(Vector2.right * moveForce);
