Could Somebody help me make my character jump?

using UnityEngine;
using System.Collections;

public class Moves : MonoBehaviour {

	public float speed = 2f;
	public float jumpHeight = 300f;
	public float movementAmount = 0.001f;
	public Rigidbody rb;
	public bool isGrounded;
	public LayerMask whatIsGround;
	public Transform groundCheck;
	public float distToGround;


	private void Start()
	{
		rb = GetComponent<Rigidbody>();
	}
	// Check for space presses in the update loop!
	void Update()
	{

		isGrounded = Physics.Raycast (transform.position, -Vector3.up, distToGround + 0.1f);

		float h = Input.GetAxis ("Horizontal");
		rb.velocity = new Vector3 (h * speed, rb.velocity.y, rb.velocity.z);

		float v = Input.GetAxis ("Vertical");
		rb.velocity = new Vector3 (rb.velocity.x, rb.velocity.y, v * speed);

		if (Input.GetKey ("space") && isGrounded) {
			rb.AddForce (0, jumpHeight, 0);
		}
	}
}

I’m pressing space, but my cube isn’t jumping at all. Are there any errors I don’t know about?

You can use ForceMode attribute and change you force adder

private bool TryJump()
    {
        float DisstanceToTheGround = GetComponent<Collider>().bounds.extents.y;

        bool IsGrounded = Physics.Raycast(transform.position, Vector3.down, DisstanceToTheGround + 0.1f);

        if (IsGrounded)
        {
            Vector3 JumpVector = Vector3.up * JumpForce;

            GetComponent<Rigidbody>().AddForce(JumpVector, ForceMode.Impulse);

            Debug.Log("Jump");

            return true;
        }

        return false;
    }
