The invariance of physical laws posits that the fundamental laws of physics are the same for all observers, regardless of their relative motion or position in the universe. This principle is foundational to modern physics, underpinning theories such as relativity and quantum mechanics, and ensures the consistency and predictability of physical phenomena across different frames of reference.

Relative motion refers to the calculation of the motion of an object as observed from a particular frame of reference, which itself may also be in motion. Understanding relative motion is crucial for accurately describing and predicting the behavior of moving objects in physics, as it emphasizes that motion is not absolute but depends on the observer's point of view.

Quantum mechanics is a fundamental theory in physics that describes the physical properties of nature at the smallest scales, such as atoms and subatomic particles. It introduces concepts like wave-particle duality, uncertainty principle, and quantum entanglement, which challenge classical intuitions about the behavior of matter and energy.

Predictability of physical phenomena

Frames of reference are systems or perspectives used to measure and observe physical phenomena, crucial for accurately describing motion and forces. They can be inertial, where Newton's laws hold true, or non-inertial, where fictitious forces are introduced to account for acceleration.
