What is a Kilonewton? 🤔
Imagine you’re trying to lift a heavy object, and you need to know how much force is required. That’s where kilonewtons (kN) come in! A kilonewton is a unit of force equal to 1,000 newtons. It’s used to measure forces that are too large for newtons alone. Just like how we use kilometers for long distances, kilonewtons are handy for measuring big forces. For instance, when an engineer calculates the load-bearing capacity of a bridge or the thrust of a rocket engine, they use kilonewtons. 🏗️🚀
Common Units of Kilonewton 🌍
