Laggy Player Movement

Hi. I am working on a 2d mobile game. I am using the rigidbody 2d for the movement:

rb.velocity = new Vector2(Speed , rb.velocity.y); // Speed = 9f

But if i start the game (whether in the editor or built as .apk or .exe) the movement is not smooth. It doesn’t look smooth it looks very laggy
… can s.o help me? Thanks
