Does this sentence has voice issues?

Question

The ball was hit by the boy.

Plz help explain

The ball was hit by the boy.

This sentence is in PASSIVE VOICE; that is, the subject is not doing the action of the verb. (Subject = ball; verb = hit)

It would be better to put the whole idea into ACTIVE VOICE: The boy hit the ball. It's always better to have the subject doing the action of the verb.
