Creating a variable jump using deltaTime in C#.

Hey everyone, I'm currently working on a game for my college project (some of you may know from my previous question) and I want to create a variable jump height that is controlled using deltaTime. So the longer the player holds the spacebar down, the higher the jump will be. My current code is below and I am basically stumped from here, any help will be greatly appreciated. Thank you.` private bool Jumping; private bool falling;

 // Use this for initialization
 void Start () {

     Jumping = false;//start off not jumping
     Falling = false;//start off not falling
 }
 
 // Update is called once per frame
 void Update () {
     print (transform.position.y);

     if (Input.GetKeyDown (KeyCode.Space)) { //if the player presses the Space Bar
         if (!Jumping) { //and if you're not already jumping
             rigidbody.AddForce(0, 500, 0);//apply an upward force to the runner
             Jumping = true;//now you're jumping
         }
         print ("Falling");

         if (!Jumping && transform.position.y>0.5) {//if the player has released the space bar after jumping
             Falling = true;//then the player is falling
         //if (Input.GetKeyDown (KeyCode.Space) && transform.position.y<1.6){//if jumping and player is higher than 3 
             //rigidbody.AddForce(0, 300, 0);//apply more upward force
         //}
     }
 }

 void OnCollisionEnter (){ //when the player collides with anything
     Jumping = false;//then you are not jumping
     Falling = false;//then you are no longer falling 

     }
 }`

I have applied a change to this coding, trying to keep it as basic as possible.` public Vector3 jumpVelocity; private bool touchingPlatform;

 // Use this for initialization
 void Start () {

     touchingPlatform = true;
 }
 
 // Update is called once per frame
 void Update () {

     if (Input.GetButtonDown ("Jump")) { //if the player presses the Space Bar
         if (touchingPlatform) { //and if you're touching the platform
             rigidbody.AddForce(jumpVelocity, ForceMode.VelocityChange);//apply an upward force to the runner
         }
     }
 }

 void OnCollisionEnter (Collision col){ //when the player collides 
     if (col.gameObject.name == "cube") {//with a game object called cube
         touchingPlatform = true;//then you are touching the platform
     }
 }
