Y velocity going crazy when landing on a surface.

Hey there, so I have this rocket ship (It's just a triangle right now). When it lands on a surface It's Y velocity becomes something like "7.806205e-09" and never stops even though I'm not moving. I really need help sorting this out because I'm checking if the velocity magnitude is less than "0.9f" and if it is then I debug.log something "Landed" however that never happens because of this issue.

My ship code:

Code (CSharp):

1. public class ModuleController : MonoBehaviour
2. {
3.     Rigidbody2D rb;
4.  
5.     [SerializeField]
6.     private float _upwardsForce;
7.     [SerializeField]
8.     private float _fuel;
9.     [SerializeField]
10.     private float _currentVelocity;
11.  
12.     [SerializeField]
13.     private Text _fuelText;
14.     [SerializeField]
15.     private Text _velocityText;
16.  
17.     private void Start()
18.     {
19.         rb = GetComponent<Rigidbody2D>();
20.     }
21.  
22.     private void Update()
23.     {
24.         _fuelText.text = "Fuel: " + _fuel.ToString("0.0");
25.         _velocityText.text = "Velocity: " + rb.velocity.ToString("0.000");
26.  
27.         _currentVelocity = rb.velocity.magnitude;
28.  
29.         //RotateModule();
30.     }
31.  
32.     private void FixedUpdate()
33.     {
34.         UpwardsForce();
35.     }
36.  
37.     private void UpwardsForce()
38.     {
39.         if (Input.GetKey(KeyCode.W))
40.         {
41.             if (_currentVelocity > 3.5f)
42.                 return;
43.  
44.             if (_fuel > 0)
45.             {
46.                 rb.AddForce(transform.up * _upwardsForce, ForceMode2D.Force);
47.                 _fuel -= 0.5f;
48.             }
49.         }
50.         else if (Input.GetKey(KeyCode.A))
51.         {
52.             if (_currentVelocity > 2.5f)
53.                 return;
54.  
55.             if (_fuel > 0)
56.             {
57.                 rb.AddForce(-transform.right * _upwardsForce, ForceMode2D.Force);
58.                 _fuel -= 0.2f;
59.             }
60.         }
61.         else if (Input.GetKey(KeyCode.D))
62.         {
63.             if (_currentVelocity > 2.5f)
64.                 return;
65.  
66.             if (_fuel > 0)
67.             {
68.                 rb.AddForce(transform.right * _upwardsForce, ForceMode2D.Force);
69.                 _fuel -= 0.2f;
70.             }
71.         }
72.     }
73.  
74.     private void RotateModule()
75.     {
76.         if (Input.GetKey(KeyCode.Q))
77.         {
78.             transform.rotation *= Quaternion.Euler(0f, 0f, 1f);
79.             _fuel -= 0.1f;
80.         }
81.         else if (Input.GetKey(KeyCode.E))
82.         {
83.             transform.rotation *= Quaternion.Euler(0f, 0f, -1f);
84.             _fuel -= 0.1f;
85.         }
86.     }
87.  
88.     private void OnCollisionEnter2D(Collision2D collision)
89.     {
90.         if (collision.gameObject.CompareTag("Surface"))
91.         {
92.             if (rb.velocity.magnitude < -1.4f)
93.             {
94.                 Debug.Log("Safely Landed!");
95.             }
96.             else if (rb.velocity.magnitude > -1.6f)
97.             {
98.                 Debug.Log("Crashed!");
99.             }
100.         }
101.     }
102. }

 

Thank you!
