Empirical laws and scientific laws are often the same thing. “Laws are descriptions — often mathematical descriptions — of natural phenomenon,” Peter Coppinger, associate professor of biology and biomedical engineering at the Rose-Hulman Institute of Technology, told Live Science. Empirical laws are scientific laws that can be proven or disproved using observations or experiments, according to the Merriam-Webster Dictionary. So, as long as a scientific law can be tested using experiments or observations, it is considered an empirical law.
