1. Your Pen or Pencil: When you write, you exert a force of pressure on the pen or pencil to create marks on the paper. This force is necessary to transfer ink or graphite from the writing instrument to the paper.
2. Your Laptop or Textbook: When you type on a laptop or turn pages in a book, you're applying a force of push or pull. For the laptop, you might be pushing on the keys to activate them, and for the textbook, you're pulling on the pages to turn them.
