Guides & comparisons

Ohmsches Gesetz verstehen: Spannung, Strom und Widerstand

Voltage drives current through resistance in a simple linear relationship. This guide covers V = IR, unit conversions, and basic circuit analysis.

Grundlagen der Wurfbewegung für Physik-Hausaufgaben

Projectiles follow parabolic paths when air resistance is ignored. Decompose motion into horizontal and vertical parts to solve homework problems.

Force vs weight (de)

Weight is a specific force — gravity on mass. Force is broader. Learn why kg is not a force and why astronauts are weightless but not massless.

Velocity vs speed (de)

Speed is how fast; velocity includes direction. Learn why average speed ≠ magnitude of average velocity on curved paths.
