Slipped

The book slipped from his lap and onto the floor.

He slipped on the wet steps and tumbled down the stairs.

She slipped on the rug and nearly fell down the stairs.

He slipped the ring from his finger and into the box.

He slipped into his pajamas and crawled into bed.

She slipped on the wet spot in the kitchen and dropped the dishes she was carrying.

I slipped up and forgot to send the important email.
