Newton's Laws of Motion are really important in science, but they don’t always work well in today’s physics. Here are some key points to understand why:
High Speeds: When things move really fast, especially close to the speed of light, Newton’s formula (, which means Force equals mass times acceleration) isn't enough.
Tiny Particles: For things that are super small, like atoms, Newton’s laws don’t apply. Instead, we use a different set of rules called quantum mechanics.
Changing Motion: When things are speeding up or slowing down, there are extra forces that seem to appear, like centrifugal force. This makes it complicated to use Newton’s Laws in these situations.
These examples show that we need new ideas and methods beyond what Newton initially gave us.
