Smartphones vibrate when they get a message because there's a special sensor inside that tells the phone to shake. It’s like having a tiny motor in your pocket that only turns on when you need it, like when your mom calls, and you’re in class!
Examples
- Your phone buzzes when you get a message because it knows someone is talking to you.
- When your friend texts you during class, your phone vibrates so you can feel it in your pocket without looking.
- You tap on the screen of your phone and it starts vibrating, like a little motor inside is saying ‘Hey, I’m here!’
