How to make a "smooth" movement of an object?

Question

Unity

Now the player can move the object, but it's not smooth enough. How to make it smoother?

The code

using UnityEngine;

public class Grabbing : MonoBehaviour
{
    [SerializeField] float maxDistance;
    [SerializeField] float GrapPower;
    [Space] 
    [SerializeField] Transform Offset;

    Transform GrabObj;
    RaycastHit hit;
    bool grab;

    private void FixedUpdate()
    {
        if (Input.GetKeyDown(KeyCode.Mouse0) || grab)
        {
            Grab();
        }
        if (Input.GetKeyDown(KeyCode.E) && grab)
        {
            Put();
        }
    }

    private void Grab()
    {
        var ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        Physics.Raycast(ray, out hit, maxDistance);
        if(grab)
        {
            GrabObj.position = Offset.position;
        }
        else if(hit.rigidbody)
        {
            grab = true;
            hit.rigidbody.useGravity = false;
            Offset.position = hit.transform.position;
            GrabObj = hit.transform;
        }
    }


    private void Put()
    {
        GrabObj.GetComponent<Rigidbody>().useGravity = true;
        grab = false;
    }
}

If you are going to move RigidBody not according to physics, then you should not turn off gravity, but activate kinematic.
