1. The Principle of Relativity

Explanation

The principle of relativity states that the laws of physics are the same for all observers, regardless of their relative motion. This means that whether you are standing still or moving at a constant speed, the physical laws apply uniformly.

Example

Imagine you are in a smoothly moving train and you toss a ball straight up in the air. To you, it appears to go straight up and down. To an observer standing outside the train, the ball follows a curved path while it rises and falls. Despite these different perceptions, the physical behavior of the ball follows the same laws of motion.
