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 key into the lock and turned it quietly.

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

The piece of paper slipped from the bulletin board and fluttered to the ground.

He slipped his backpack off his shoulder and onto the ground.
