how do i rotate and movement together

hi i have a 2d sprite i want that rotate (always with variable rotatespeed) and i want that move forward (right) with variable movespeed (sprite is rigidbody and circle collider 2d ) i use this c# code but it not working well :

 using UnityEngine;
 using System.Collections;
 
 public class movescript : MonoBehaviour {
     
     /// Scrolling speed
     public Vector2 speed = new Vector2(2, 2);
 
     /// Moving direction
     public Vector2 direction = new Vector2(-1, 0);
 
     void Update()
     {
 
         // Movement
         Vector3 movement = new Vector3(speed.x * direction.x,speed.y * direction.y,0);
         
         movement *= Time.deltaTime;
 
         transform.Rotate (0,0,10);
 
         transform.Translate(movement);
 
     }
 
 }
