Real-World Examples of Newton’s First Law of Motion

1. A Book on a Table

   • Issue: The book just sits still on the table until someone pushes or moves it. This can be a bit annoying if you want to use it.
   • Tip: Knowing that any push or pull can make the book move helps us understand how things work.

2. Passengers in a Car

   • Issue: When a car suddenly stops, passengers might jerk forward. This shows how inertia affects us.
   • Tip: Wearing seatbelts can help prevent injuries. It’s a good reminder of why safety gear is important.

3. A Hockey Puck on Ice

   • Issue: The puck slides across the ice but eventually stops because of friction. Many players find this frustrating during a game.
   • Tip: Understanding that friction slows things down can make us think about using smoother ice to play better.

These examples help us see how inertia works and why we sometimes need to push or pull to get things moving.
