Object starts to swerve/gets derailed after collision with a collider. Please help!

Hi!

I need help to figure out why my object starts to swerve/gets derailed after collision with collider. ie. my object travels straight line but after small collision to the right side it starts straifing right. I dont want this to happen. Any idea? My game is for Android if that matters.

Here is a GIF so you can see what i mean: https://gyazo.com/c46533a75436c7ce9f22afda753bbe5a

Player (object) movement script:

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityStandardAssets.CrossPlatformInput;

public class player : MonoBehaviour {

 [SerializeField]
 public static float moveSpeed = 1f;

 [SerializeField]
 float angularSpeed = 2f;

 float rotationX;

 Rigidbody2D rb;

 // Use this for initialization
 void Start () {
     rb = GetComponent<Rigidbody2D>();
     
 }
 
 // Update is called once per frame
 void Update () {
     rotationX = CrossPlatformInputManager.GetAxis("Horizontal");
     transform.Rotate(0, 0, rotationX * angularSpeed);
 }
 void FixedUpdate()
 {
     rb.velocity = transform.up * moveSpeed;
 }

 public void OnCollisionEnter2D(Collision2D collision)
 {
     if (collision.gameObject.tag.Equals("rock"))
     {
         // how much the character should be knocked back
         var magnitude = 500;
         // calculate force vector
         var force = transform.position - collision.transform.position;
         // normalize force vector to get direction only and trim magnitude
         force.Normalize();
         gameObject.GetComponent<Rigidbody2D>().AddForce(force * magnitude);
     }
 }

}
