A quick look at how physics reveals the rules behind motion, energy, matter, light, and the universe—and turns those rules into useful technology.
Physics asks why objects move, waves travel, materials behave differently, and stars shine. It turns observations into models that can explain events and predict what may happen next.

Wende das Gelernte aus der vorherigen Lektion auf reale Probleme an.
Energy can change from motion to heat, light, sound, or electricity, yet the total is conserved. This powerful idea connects roller coasters, batteries, food, engines, and distant stars.
GPS uses relativity, phones rely on electromagnetism and quantum physics, and buildings depend on forces and materials. Everyday tools often work because physical effects can be measured and controlled.
Physics reaches from particles smaller than atoms to galaxies spanning millions of light-years. Questions about quantum uncertainty, black holes, time, and the origin of the universe show how strange nature can be.
Physicists and physics-trained people work in research, engineering, medicine, energy, climate science, computing, education, and space technology. They build instruments, analyze evidence, simulate systems, and solve problems in collaborative communities.
