1261 - Why do objects maintain their original state of motion when no force is applied?

This is called Newton's First Law, or the Law of Inertia. It says that objects will stay still or keep moving in the same way unless a force is applied to them.

Think of it like this: Imagine you're sitting on a skate in a big empty space with no friction. If you're not moving, you'll stay still. If you're moving, you'll keep moving in the same direction and speed until something (like the ground or a wall) stops you or changes your direction.
