Hello, I’m messing around in Unity and I want force to apply to a cube only one when i press “s”

I have tried this following method:

public float force = 5000f;

if (Input.GetKeyDown (KeyCode.S))
rb.AddForce(0, 0, force);
Debug.Log(“Launch”);

if (force > 5000)
force = 5000;

if i repeatedly “s” then the force will increase by increments of 5000 rather than staying at 5000 now matter how many times i press the s key.

using UnityEngine;

public class player : MonoBehaviour
{
    public Rigidbody rb;
    public float force = 5000;
    public float sideforce = 500;
   

    // Start is called before the first frame update
    void Start()
    {
       
    }

    // Update is called once per frame
    void FixedUpdate()
    {
            rb.AddForce(0, 0, force);
            Debug.Log("Launch");

        if (Input.GetKey(KeyCode.RightArrow))
        {
            Debug.Log("Left Movement");
            rb.AddForce(sideforce * Time.deltaTime, 0, 0);
        }

        if (Input.GetKey(KeyCode.LeftArrow))
        {
            Debug.Log("Right Movement");
            rb.AddForce(-sideforce * Time.deltaTime, 0, 0);
        }

    }
}

Thank you

found the solution, had to change it to
if (Input.GetKeyDown(KeyCode.S))
{
rb.AddForce(force * transform.forward);
}
