Instantiated object won't move!

Hi all,

I am trying to get an instantiated object (prefab) to travel in the direction its facing, however when it instantiates the object it doesn't move. I cannot figure out why. My code is below, thanks in advance:

 using UnityEngine;
 using System.Collections;
 
 public class PlayerMovement : MonoBehaviour
 {
     // Movement Speed and Force applied when hit!
     public float moveForce = 365f;            // Amount of force added to move the player in all directions.
     public float maxSpeed = 5f;                // The fastest the player can travel in the both axis.
 
     public Rigidbody2D Arrow;
     public float projSpeed = 50f;
     // Arrows
     public int arrowAmmo = 20;
     public bool CanFire = false;
 
     // Rotation Variables
     private Vector3 mousePos;
     private Vector3 lookPos;
     private float mouseX;
     private float mouseY;
     public float angle;
 
     void Awake()
     {
         //anim = GetComponent<Animator>();
     }
     
     
     void Update()
     {
         InputControl();
         RotationControl();
 
     }
     
     void FixedUpdate ()
     {
 
     }
 
     void RotationControl ()
     {
         // Updates Mouse Co-ordinates
         mousePos = Input.mousePosition;
 
         // Set out Mouse Position.z variable to 0 as it is not needed.
         mousePos.z = 0;
 
         // Using lookPos we allow the object to transoform its position.
         lookPos = Camera.main.ScreenToWorldPoint(mousePos);
         lookPos = lookPos - transform.position;
 
         // Setting up the angle using both the y and x co-ords multiplied by 57.2... stored as Rad2Deg by Unity
         angle = Mathf.Atan2(lookPos.y, lookPos.x) * Mathf.Rad2Deg;
 
         // Finally Rotate the object by using a quaternion angle axis which uses the angle variable as well as the vector3.forward
         transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
     }
 
     void InputControl()
     {
         // later on check the game state and make sure we are in game playing and not paused :)
 
         // Left
         if(Input.GetKey ("a"))
         {
             // Set movement speed
             transform.position -= Vector3.right * maxSpeed * Time.deltaTime;
         }
         if(Input.GetKey ("d"))
         {
             // Set Movement speed using the max speed and delta timer
             transform.position += Vector3.right * maxSpeed * Time.deltaTime;
         }
         if(Input.GetKey("w"))
         {
             transform.position += Vector3.up * maxSpeed * Time.deltaTime;
         }
         if(Input.GetKey("s"))
         {
             transform.position -= Vector3.up * maxSpeed * Time.deltaTime;
         }
         if(Input.GetMouseButton(1) && arrowAmmo > 0)
         {
             Rigidbody2D arrowInstance = Instantiate(Arrow, transform.position, transform.rotation) as Rigidbody2D;
             arrowInstance.AddForce(transform.forward * 6);
         }
     }
 
 }
