Question How to reduce "bounciness" on this hover effect?

Code (CSharp):

1. void Update()
2.     {
3.         if (grounded)
4.         {
5.             playerRB.velocity = new Vector2(playerRB.velocity.x, force);
6.         }
7.     }
8.  
9.     private void OnTriggerEnter2D(Collider2D collision)
10.     {
11.         if(collision.tag == "Ground")
12.         {
13.             grounded = true;
14.         }
15.     }
16.  
17.     private void OnTriggerExit2D(Collider2D collision)
18.     {
19.         if(collision.tag == "Ground")
20.         {
21.             grounded = false;
22.         }
23.     }

This code is for a script attached to an object with a tiny Box Collider 2D, which is the child of another object with a Rigidbody 2D. The former object is positioned below the parent object. The desired effect is a smooth hover of the parent object. What I don't like about this one is that it moves (or "bounces") too much. I know this code is simple. I tried multiple things, but I have discarded all of my attempts and decided to post the initial, simplistic one here.

tl;dr: want smoother movement

 

Update: I think I'll use Raycasts after all to achieve the hover effect. I was trying to find an alternative, but i think Raycasting might be simpler after all.
