What do experience have in common with observation, and how do they differ from each other? Give examples

When conducting an experiment, we create special conditions for the flow of the physical phenomena of interest to us, for example, we take two bodies of different masses. The experiments we set out to check the validity of the hypothesis put forward on the basis of observation, for example, – heavy bodies fall faster. To confirm or refute the hypothesis, repeated repetition of the experiment is necessary.
