Projectile not moving properly in top down 2d shooter

Questions & Answers
1

I am working on this 2d top down shooter and cannot get the shooting mechanics to work. The bullets spawn in the correct rotation and position but they do not move at all. nothing.
I would very much appreciate it if someone could tell me what I am doing wrong.

if (Input.GetButtonDown ("Fire1")) {
			if (currentWeapon == 1 & pistolAmmo >= 1){
				GameObject Bullet = (GameObject)Instantiate(Projectile, playerSprite.transform.position, player.transform.rotation);
				Bullet.GetComponent<Rigidbody>().AddForce(player.transform.forward * bulletSpeed * Time.deltaTime);
			}

I can post the rest of the code if it will help. Thank you in advance.

P.S Sorry for bad English

As a starting point, make sure that your bullets have a non-kinematic rigidbody.

The line

GameObject Bullet = (GameObject)Instantiate(Projectile, playerSprite.transform.position, player.transform.rotation);

should be

Rigidbody Bullet = Instantiate(Projectile, playerSprite.transform.position, player.transform.rotation) as Rigidbody;

Spawn the object as a Rigidbody and then apply force that way.

if (Input.GetButtonDown ("Fire1")) {
    if (currentWeapon == 1 & pistolAmmo >= 1){
        Rigidbody Bullet = Instantiate(Projectile, playerSprite.transform.position, player.transform.rotation) as Rigidbody;
       Bullet.GetComponent<Rigidbody>().AddForce(player.transform.forward * bulletSpeed * Time.deltaTime);
    }
