Question

what do you understand by zero point energy​

Answer 1

Zero-point energy (ZPE) is the lowest possible energy that a quantum mechanical system may have. Unlike in classical mechanics, quantum systems constantly fluctuate in their lowest energy state as described by the Heisenberg uncertainty principle.

Answer 2

Explanation:

Scientific definitions for zero-point energy. zero-point energy. The irreducible minimum energy possessed by a physical system, as of a substance at a temperature of absolute zero. The zero point energy of a vacuum is not zero due to vacuum fluctuations.
