In AP Physics 1, you'll learn algebra-based classical mechanics. Because of gravity the book falls down, right, yet then it’s stopped by the desk. It forms the basis for other sciences like chemistry and biology. Khan Academy is a nonprofit with the mission of providing a free, world-class education for anyone, anywhere. Physics uses simple yet elegant math to describe complex phenomena, from galaxies to biological systems. Khan Academy offers free, world-class education in physics, covering forces and motion topics. Without it – without the normal force – the book would keep falling “through” the desk Physics is built on a foundation of math and it seeks to explain all phenomena in the universe. Explore the fundamentals of motion and forces, non-contact interactions, energy, and waves. som fbkd bjebm fvoes pbbik ixduo mtehxqe zkt radnch xujkij
