A more thorough explanation:

The law of nature, also known as natural law, can refer to both physical laws of nature and philosophical systems of legal and moral principles.

A physical law of nature refers to a fundamental principle that governs the behavior of the natural world. For example, the law of gravity is a physical law of nature that explains why objects are attracted to each other.

A philosophical system of natural law is a set of legal and moral principles that are believed to be inherent in human nature or divine justice, rather than created by legislative or judicial action. For example, many ethical teachings are based on natural law, which embodies principles of right and wrong.

One example of natural law is the belief that all humans have the right to life, liberty, and the pursuit of happiness. This principle is believed to be inherent in human nature and is therefore considered a natural law.

Another example of natural law is the belief that it is wrong to kill another person. This principle is believed to be inherent in human nature and is therefore considered a natural law.

Overall, the law of nature refers to fundamental principles that govern the behavior of the natural world and the moral and legal principles that are believed to be inherent in human nature or divine justice.
