I have tried to make a 2D PlayerMovement script and my jumping mechanics doesn’t work.

Please let me know what to change.

using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    [SerializeField] private float speed;
    private Rigidbody2D body;

    private void Awake()
    {
        body = GetComponent<Rigidbody2D>();
    }

    private void Update()
    {
        body.velocity = new Vector2(Input.GetAxis("Horizontal") * speed, body.velocity.y);

        if (Input.GetKey(KeyCode.Space))
        {
            body.velocity = new Vector2(body.velocity.x, speed);
        }
    }
}

so you can do this code:

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(Rigidbody))]
public class PlayerController : MonoBehaviour {
    public Vector3 jump;
    public float jumpForce = 2.0f;

    public bool isGrounded;
    Rigidbody rb;
    void Start(){
        rb = GetComponent<Rigidbody>();
        jump = new Vector3(0.0f, 2.0f, 0.0f);
    }

    void OnCollisionStay(){
        isGrounded = true;
    }

    void Update(){
        if(Input.GetKeyDown(KeyCode.Space) && isGrounded){

            rb.AddForce(jump * jumpForce, ForceMode.Impulse);
            isGrounded = false;
        }
    }
}
