Can someone help me fix this coding error?

Before I show the code, I would like to explain I did try to fix it and my fix worked kind of, but caused other errors to show up and I just didn’t feel like typing all of the errors out on here and I already know it wasn’t the right kind of fix I needed.
Anyways, here is the code I used

#pragma strict
 
 var rotationSpeed = 100;
 var jumpHeight = 8;

 private var isFalling = false;

 function Update () 
 {
 	//Ball rotation.
     var rotation : float = Input.GetAxis ("Horizontal") * rotationSpeed;
     rotation *= Time.deltaTime;
     var rigidbody: Rigidbody = gameObject.GetComponent(Rigidbody) as Rigidbody;
	GetComponent.<Rigidbody> ().AddRelativeTorque (Vector3.back * rotation);

	if (Input.GetKeyDown(KeyCode.Space));

	{
		Rigidbody.velocity.y = jumpHeight;
	}
	isFalling = true;
 }

And the error that showed up is “An instance of type ‘UnityEngine.Rigidbody’ is required to access non static member ‘velocity’”

Rigidbody.velocity.y = jumpHeight;

=>

rigidbody.velocity.y = jumpHeight;

Rigidbody is the name of the class, rigidbody in this case is the name of the variable.
