The problem is that you cannot assign cause to your effect. What Is an Experiment? How does it behave? The hypothesis should be clear and precise to consider it to be reliable. Very high standard yet easily understandable explanation. Probably not, since it is so hard to assign cause and effect. If physics (as you say) is “what explains mechanics”, then physics is what “experimental philosophy” was about 400 years ago. Hypothesis is an assumption that is made on the basis of some evidence. It includes components like variables, population and the relation between the variables. Examples of Hypothesis. Ask a question. Physics is the study of matter — what is it made of?
