Distinguishing Scientific Laws from Theories

The video explains the difference between scientific theories and laws, highlighting that laws predict outcomes while theories explain why things happen. It discusses how theories and laws serve different purposes in science, using Kepler's work as an example. The video also covers the acceptance and evolution of theories, the value of incorrect theories, and the future adaptability of scientific theories.

What is the primary difference between a scientific theory and a scientific law?

• A theory predicts what happens, while a law explains why.

• A law predicts what happens, while a theory explains why.

• A theory is always correct, while a law can be wrong.

• A law is always correct, while a theory can be wrong.

Which of the following is an example of a scientific law?

• Theory of Relativity

• Law of Gravity

• Big Bang Theory
