Channel Title: GetAClass - Physics Channel Description: 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. <video> Gravity centre Description: Thank you for your interest in our work!

Breathe Himalayan-like air even in Central Delhi. </video> <video> Why do planes fly so high? Description: Why do passenger planes usually fly at an altitude of 10-11 km? Because there the air density is 3 times less, which means the air resistance at the same speed is 3 times less. By the way, why don’t they fly even higher? Key words: air resistance, standard atmosphere. Thank you for your interest in our work!

Description: People learned that the Earth is a ball by observing the shape of the Earth's shadow during lunar eclipses and the change in the starry sky as we move between northern and southern latitudes. And the diameter of the Earth was first measured by Eratosthenes of Cyrene, and we tell you how he did it. Thank you for your interest in our work!
