Physics using Time.deltaTime?

Hi, I just wanted to know if there’s a difference between multiplying by Time.deltaTime in Update() my physics or leaving them in FixedUpdate() and multiplying them by Time.fixedDeltaTime.

Example:

void FixedUpdate()
{
	GetComponent<Rigidbody2D>().AddForce(Vector2.right * 50f * Time.fixedDeltaTime, ForceMode2D.Impulse);
}

or

void Update()
{
	GetComponent<Rigidbody2D>().AddForce(Vector2.right * 50f * Time.deltaTime, ForceMode2D.Impulse);
}

Well, I tried attaching both scripts to 2 boxes and they moved the same… it seems it’s the same…
