A scientific law is formed when the results of an experiment generate the same results every time a particular experiment is performed. A scientific law is made when something has been thoroughly tested again and again through experimentation. Unlike the theory, a scientific law is not subjected to change with time. A scientific law is accepted universally and other hypothesis can be generated based on the authenticity of the law.
