Newton's First Law of Motion, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity, unless acted upon by a net external force. Here are some everyday examples:
1. **A book on a table**: A book sitting still on a table will remain at rest until someone picks it up or pushes it.
2. **A passenger in a car**: When a car suddenly stops, passengers lurch forward. Their bodies tend to continue moving at the same speed the car was going due to inertia.
3. **A soccer ball on the ground**: A soccer ball will remain still on the ground until someone kicks it (applying a force), causing it to move.
4. **A rolling ball**: A ball that is rolling on a flat surface will eventually come to a stop due to friction (a force acting on it). If friction were negligible, it would continue rolling indefinitely.
5. **A cup of coffee on a bus**: If a bus suddenly accelerates, the cup of coffee may tilt or spill because the coffee inside the cup was at rest relative to the bus at that moment. The cup moves forward while the coffee tends to stay in place until it is pushed by the cup.
6. **Objects inside a moving vehicle**: Items in the trunk of a car will remain in place until the car accelerates around a turn or comes to a sudden stop.
7. **Spacecraft in space**: A spacecraft that is coasting in space will continue moving forward in a straight line at a constant speed until acted upon by gravitational forces or its thrusters.
8. **A hockey puck on ice**: A puck sliding on ice will continue gliding across the surface until friction or another player's stick stops it.
These examples illustrate how the concept of inertia plays a significant role in our everyday experiences and interactions with objects around us.
