For the error you mention to go away you need to remove the last } in your code. You will also need to declare a namespace and a class as you cannot declare fields and methods without those. You should also initialize your RigidBody . In the end your code should look something like this:

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

namespace SomeNamespace
{
    public class SomeClass
    {
        public RigidBody rb;

        public float forwardForce = 2000f;
        public float sidewaysForce = 2000f;

        void Start()
        {
            /// Initialize rb here
        }
        void Update()
        {
            rb.AddForce(0, 0, forwardForce * Time.deltaTime);

            if (Input.GetKey("w"))
            {
                rb.AddForce(500 * Time.deltaTime, 0, 0);
            }
        }
    }
}
