@estherara,
You're absolutely correct! The sentence doesn't quite make sense as it's redundant. When something is "dropped," it means it has fallen from a higher position to a lower one. So, saying "a dropped object is any item that falls" is repetitive because dropping already implies falling.
You could simplify the sentence by saying something like: "A dropped object is any item that falls from a height." This version keeps the meaning clear without the redundancy.
