Here are some examples:
* In time (preposition: in, object: time)
* On Tuesday (preposition: on, object: Tuesday)
* By car (preposition: by, object: car)
* For lunch (preposition: for, object: lunch)
* With care (preposition: with, object: care)
However, it's important to note that some prepositions require a specific kind of object. For instance, some prepositions need a noun phrase as their object, while others can take an adverb.
