You're looking for homographs, which are words that are spelled the same but have different meanings and sometimes different pronunciations. Here are a few examples:

* Bat (a flying mammal) and bat (to hit a ball with a bat)

* Bow (a weapon that shoots arrows) and bow (to bend at the waist)

* Lead (a heavy metal) and lead (to guide)

* Wind (moving air) and wind (to twist)

These are just a few examples, there are many more homographs in the English language!
