Newton’s Laws of Motion
Fun Facts
- A kicked ball moves due to a force applied.
- A heavier child on a swing needs more force to reach the same height.
- A rocket moves up when gases push down on Earth with equal force.
Why Do We Need To Know About Motion
Learning about how things move helps us understand everyday life and why some jobs depend on this knowledge. Jobs like engineering need a grasp of how things move and work together to make things we use every day.
This isn’t just school stuff; it has real uses that keep us safe and make our lives easier. For example, engineers who work on making cars safer use the rules of motion to design features that protect us in a crash. These include parts of the car that squish to absorb shock and systems that warn us before we hit something. This helps them figure out how to reduce the impact of a crash and save people’s lives.
