Webb16 nov. 2024 · With Friday's vote, scientists redefined the kilogram for the 21st century by tying it to a fundamental feature of the universe — a small, strange figure from quantum physics known as Planck's constant, which describes the smallest possible unit of energy. The kg is dead, long live the kg. Watch on. Thanks to Albert Einstein's revelation that ... Webb2 aug. 2024 · Vector, in physics, is defined as any quantity that is described by both a number and a direction. Examples of a physical vector are displacement, velocity, and acceleration . In contrast, there are quantities that are fully described merely by a number like distance, speed, temperature, time, and mass. These are called scalars.
