Abstract: Weakly projective property of acts is investigated, the conditions that preserve weakly projective property under coproducts and products are discussed, and transitivity of weakly projective property on Rees short exact sequences is also considered.

Key words: weakly projective, coproduct, product, Rees short exact sequence
