More smooth movement in 2D

Hello, I want a more smoother movement in my 2D game. I created a rigidbody 2D and changed the Gravity to 0 because I dont want that I fall down. When I move it is smooth but I want that the movement is more delayed. For example I press A Im going left then I release the button but Im still moving(for 1-2 seconds) in that way.

I hope you could understand what I try to do, my script for moving the player is here, I dont use GetAxisRaw because it stops immediately when I release so i choosed only GetAxis.

Code (CSharp):

1. public class bewegen : MonoBehaviour
2. {
3.  
4.     public float speed = 4.0f;
5.  
6.     // Update is called once per frame
7.     void Update()
8.     {
9.        
10.     }
11.  
12.     private void FixedUpdate()
13.     {
14.  
15.         Vector3 movement = new Vector3(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"), 0);
16.         transform.position += movement * speed * Time.deltaTime;
17.        
18.     }
19. }
20.  

I'm new to coding so please dont be you know....

Thanks for your answers.
