how to find velocity of an object in code unity code example

Example 1: unity get velocity of gameobject

Rigidbody rb = GetComponent<Rigidbody>();
rb.velocity; // Velocity of gameObject (Vector3)

Example 2: unity how to get the side ways velocity of a object

Rigidbody rb = GetComponent<Rigidbody>();
Vector3 worldVelocity = rb.velocity;
Vector3 localVelocity = transform.InverseTransformVector(worldVelocity);
//This gives velocity in all directions sideways is on the x axis the thread gives more info
