Inertia and mass are very important when we talk about Newton's First Law. Let’s break it down:
What is Inertia?
Inertia is how much an object wants to keep doing what it’s already doing. This means if something is sitting still, it wants to stay still. And if it’s moving, it wants to keep moving.
How Mass Fits In:
Mass is how we measure inertia. The heavier something is, the more inertia it has. For example, think about trying to push a big heavy boulder. It’s much harder than pushing a small light ball!
In Short:
Inertia has a lot to do with mass. More mass means more inertia, which means it takes more effort to change how the object is moving.
