In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of the phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research.
"In science, laws are a starting place, " said Peter Coppinger, an associate professor of biology and biomedical engineering at the Rose-Hulman Institute of Technology. "From there, scientists can then ask the questions, 'Why and how?'"
Scientific theory vs. scientific law
Both scientific laws and theories are supported by a large body of empirical data and are widely accepted by the vast majority of scientists within a discipline. Both also help unify a particular field of scientific study. However, theories and laws, as well as hypotheses, are separate parts of the scientific method.
"Hypotheses, theories and laws are rather like apples, oranges and kumquats: one cannot grow into another, no matter how much fertilizer and water are offered, " according to University of California. A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. A law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University.
"There are four major concepts in science: facts, hypotheses, laws, and theories, " Coppinger told Live Science. "Laws are descriptions — often mathematical descriptions — of natural phenomenon; for example, Newton’s Law of Gravity or Mendel’s Law of Independent Assortment. These laws simply describe the observation. Not how or why they work."
Coppinger pointed out that the Law of Gravity was discovered by Newton in the 17th century. This law mathematically describes how two different bodies in the universe interact with each other. However, Newton’s law doesn’t explain what gravity is, or how it works. It wasn’t until three centuries later, when Albert Einstein developed the Theory of Relativity, that scientists began to understand what gravity is, and how it works.
"Newton’s law is useful to scientists in that astrophysicists can use this centuries-old law to land robots on Mars. But it doesn’t explain how gravity works, or what it is. Similarly, Mendel’s Law of Independent Assortment describes how different traits are passed from parent to offspring, not how or why it happens, " Coppinger said.
What is the difference between scientific theory and law.
a scientific theory is sort of a minor law which has not been proven by a group of geniuses. a law on the other hand is a proven 100 % theory...........its how something works in life
