The purpose of a scientific law is to describe a consistent and universal observation in nature, expressed in a concise statement or mathematical formula. Scientific laws characterize predictable phenomena under specific conditions and are based on empirical evidence obtained through repeated experimentation and observation. Unlike scientific theories, which provide explanations for why something occurs, laws explain what happens consistently. For example, Newton's laws of motion describe the relationship between the motion of objects and the forces acting upon them. Scientific laws serve as foundational principles that help scientists understand and predict the behavior of the natural world.
