School physics: experience and experiments Physics is an experimental science. Physicists have extracted all their knowledge from experience, asking questions to nature through such experiments that make it reveal its secrets. In a school, likewise, physics is simpler to understand if each lesson begins with practice, and knowledge is acquired through experiments prior to textbooks. And even in books we can better grasp things that we made and seen by ourselves. The present video course is an encyclopedia of elementary physics for school students. Watch how we do experiments, do it with us, come up and show new ones! Listen to our reasoning, sort it out, make your own explanations and estimations. That's the best way to investigate how physics works.
