Build error in Unity 5

I'm an absolute beginner in programming and I'm trying my hand at Unity 5, but I get this error code whenever I try to build this code

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour 
{
    void FixedUpdate()
    {
        float moveHorizontal = Input.GetAxis ("Horizontal");
        float moveVertical = Input.GetAxis ("Vertical");

        Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

        Rigidbody.AddForce(movement);
    }
}

I get the "error cs0120 an object reference is required for the nonstatic field method or property" can anyone help me out with this one?

Thx!

Previous to Unity 5, "rigidBody" was a property of GameObject. Your code still wouldn't have compiled, it would have needed to be:

gameObject.rigidBody.AddForce(movement);

Because rigidBody isn't a property or field of MonoBehavior, gameObject is. Since its not in Unity 5, you'll need to use GetComponent:

RigidBody rb = GetComponent<RigidBody>();
rb.AddForce(movement);

See the documentation for more: Unity Docs

When its all said and done, the code would be:

    void FixedUpdate()
    {
        float moveHorizontal = Input.GetAxis ("Horizontal");
        float moveVertical = Input.GetAxis ("Vertical");

        Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

        RigidBody rb = GetComponent<RigidBody>();
        rb.AddForce(movement);
    }
