Game is glitching out

So I finally managed to input controls for my ball but it's super glitchy and flies around, It has rigidbody in it and Here's the code BTW:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class NewBehaviourScript : MonoBehaviour {
void Start () {


}
float speed = 0.13f;

void Update () {
var X = Input.GetAxis ("Horizontal") * speed;

transform.Translate (X, 0, 0);

}
}

 

You'll also want to multiply the speed by Time.deltaTime and increase the speed by quite a lot. You'll want your speed in units per second, where right now you have them in units per frame.

 

You'll also want to use physics forces to move your object, otherwise you're basically teleporting it and the physics engine is going to throw a fit any time it interacts with anything.
