What Is The Difference Between A Theory And A Law

The link must be confirmed by cause and effect.

The theory may be a correlation a coincidence or an actual fact that is not fully explained. 2 a theory requires experimentation under various conditions. Law explains what is nature doing under certain conditions and it can predict the future if the conditions are satisfied. A scientific law might explain the relationship between two specific forces or between two changing substances in a chemical reaction.

Theory is often descriptive and complex than laws with detailed explanation or contains several supported hypothesis. Theory explains why something happens whereas law describes what happens when certain conditions are present. However this never happens with a law. Laws are generalization about a phenomena.

Theory and law are two terms that we encounter in the field of sciences. Scientific laws differ from theories in that they tend to describe a narrower set of conditions. Theories explain the phenomena and try to back them with logic and evidence. The main difference between a law and a theory is that a theory tries to explain the reasoning behind something that occurs in nature whereas scientific laws are just descriptive accounts of how something occurs in nature.

The evidence back a theory after going through experiments under various conditions whereas a law is a simple concise statement that remains unchanged. The theory is used to explain an occurrence while the law describes a phenomenon under specific circumstances in nature.

A theory may get outdated or replaced by the other one while the law doesn t get replaced. Law a theoretical principle deduced from particular facts scientific laws are usually short mathematical expressions representing how nature will behave under certain conditions.
