My movement script is not moving my 2D object

Here is what I have so far.

 using UnityEngine;
 using System.Collections;
 
 public class PlayerControl : MonoBehaviour
 {
 
     public float movementSpeed = 10f;
 
     void Update () {
 
         if(Input.GetKey(KeyCode.UpArrow))
         {
             GetComponent<Rigidbody2D>().AddForce(new Vector2(0, 1) * movementSpeed * Time.deltaTime);
         }
     
     }
 }
 

I want my object to move up when I press the up key and it seems to do nothing when I press the key. I'm new to Unity and I think I might have just missed something.
