Newton's First Law of Motion says that things want to keep doing what they’re doing. If something is sitting still, it will stay still unless something else makes it move. If it’s moving, it will keep moving unless something stops it.

Here are some easy examples:

1. Car Stopping Suddenly: When a car stops quickly, the people inside lean forward. This happens because their bodies want to keep moving because of something called inertia.

2. A Book on a Table: If you put a book on a table, it will stay there until someone picks it up or if something pushes it off.

3. A Hockey Puck Sliding: When you hit a hockey puck on ice, it slides a long way without slowing down much. This is because there's not much friction to slow it down.

4. Sitting on a Bicycle: If you stop pedaling a bike, it will eventually stop too, unless you are going downhill where gravity gives it a little push.

These examples show how things move or stay still based on outside forces. It helps us understand how motion and rest work according to Newton's First Law!
