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 envelope from his grasp and it fell between the seats in the car.

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

She slipped her feet into the high-heeled shoes, feeling confident and elegant.

His physical condition slipped after he stopped exercising.
