Better jumping in unity 2d?

I am currently working on a 2d game, and for jumping, I'm using Rigidbody.Addforce(). However, this causes my player to land back to the ground slowly. I want it to land back quickly.

I tried manipulating the values of Gravity scale and mass, but that causes effects over player movement and again that jump doesn't come out well.

Here's the code:-

    private void Update()
    {
        if (IsGrounded == true)
        {
            extraJumps = 1;        
        }

        if (Input.GetKeyDown(KeyCode.Space) && extraJumps > 0 && PlayerCanMove == true) //Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Ended
        {
            if (CheckGrounded() == true && OnSlope() == false)
            {
                Catanim.SetBool("isJumping", true);                        
                IsJumping = true;
                RBody.AddForce(Vector2.up * JumpForce * 1000f);
                extraJumps = extraJumps - 1;
                
   
            }
            else if(CheckGrounded() == true && OnSlope() == true)
            {
                Catanim.SetBool("isJumping", true);                        
                IsJumping = true;
                RBody.AddForce(Vector2.up * JumpForce * 1000f);
                extraJumps = extraJumps - 1;
                

            }
            else
            {
                IsJumping = false;
                Catanim.SetBool("isJumping", false);
            }
        }
    }
 }

I'd recommend using a character controller and making your gravity if you are trying to make a 2D game. However, if you want to stick to rigid body and want to adjust your gravity your can do that:

 public float gMoon=1.6f;  //gravity on the moon.
     void Start()
     {
         rb=GetComponent<Rigidbody>();
     }
     void FixedUpdate()
     {
         rb.AddForce(new Vector3(0, -1.0f, 0)*rb.mass*gMoon);  
     }

In short, to make a better jump, you need a condition to determine the up and down movement. The code below is the key to solving the problem.

if (RBody.velocity.y > 0) // moving UpSide
{
    RBody.gravityScale = 1;
}
else // moving on ground
{
    RBody.gravityScale = 2; // double gravity scale for jumping down
}

And to summarize the code:

private void Update()
{
    if (IsGrounded == true)
    {
        extraJumps = 1;        
    }

    if (Input.GetKeyDown(KeyCode.Space) && ...)
    {
        ...
    }

    RBody.gravityScale = RBody.velocity.y > 0 ? 1f : 2f; // define upside gravity first and down side gravity second
}
