My investigation reveals that "bounce" has two past forms: the simple past "bounced" and the past participle "bounced." Both forms are used to denote the action of electrical waves or items recoiling after hitting a surface. In sentences, the simple past indicates an action that occurred at a specific time in the past, while the past participle is typically used in passive constructions or perfect tenses to emphasize the completion of the action.
