How would I make my player fall properly?

,I wanna make my player fall but instead, he just feathers down and gravity doesn’t take effect. I have the use of gravity checked on my rigidbody, and I skimmed through my movement script and it doesn’t seem that anything was affecting it

Code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Movement : MonoBehaviour
{


    public float Speed;
    private Rigidbody rb;
    public bool isGrounded = true;

    // Start is called before the first frame update
    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    // Update is called once per frame
    void Update()
    {
        float hmove = Input.GetAxis("Horizontal");
        float vmove = Input.GetAxis("Vertical");

        Vector3 Direction = new Vector3(hmove, 0, vmove);
        Direction.Normalize();

        rb.velocity = transform.TransformDirection(Direction * Speed);

        if (Input.GetKeyDown(KeyCode.Space) && isGrounded == true)
        {
            isGrounded = false;
            rb.AddForce(new Vector3(0, 5000, 0), ForceMode.Impulse);
        }
    }

    private void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.tag == "Ground")
        {
            isGrounded = true;
        }
    }
}

You have to set the Mass and Drag of the RigidBody in the Inspector.
Also I believe that when you do

rb.velocity = transform.TransformDirection(Direction * Speed);

You will overwrite the Y axis velocity so it becomes 0 every frame, Instead you can preserve the velocity.y

Direction.y = rb.velocity.y; //keep current Y
rb.velocity = transform.TransformDirection(Direction * Speed);

Or you could go over to using rb.AddForce() for X and Z as well.
