When we think of the quantum universe, we typically think about individual particles that also exhibit wave-like properties. But in truth, that's only part of the story; the particles aren't just quantum, but the fields and interactions between them are, too.

Web13 dec. 2024 · 4. 0. fresh_42 said: If the cars are at rest, then the total velocity before is zero. This cannot be said of the velocities after release. Velocity isn't conserved and depends on many factors. One is, that the two cars don't even have a single velocity, since the spring applies an acceleration to the cars, not a velocity.

WebFor a planet of mass m in an elliptical orbit, conservation of angular momentum implies that as the object moves closer to the sun it speeds up.
