What are the 4 major scientific laws?

The four major scientific laws often referenced are Newton's Laws of Motion, the Law of Universal Gravitation, the Laws of Thermodynamics, and the Law of Conservation of Mass. Newton's Laws describe the motion of objects, the Law of Universal Gravitation explains the attraction between masses, the Laws of Thermodynamics govern energy transfer and entropy, and the Law of Conservation of Mass states that mass cannot be created or destroyed in a closed system. These laws provide foundational principles that underpin much of classical physics and chemistry.
