## Homework Statement

Explain, using the Heisenberg Uncertainty Principle, how classical physics is reached a a limit of quantum physics when (h-bar) tends to 0.

## Homework Equations

ΔxΔp(x) ≥ (h-bar)/2

## The Attempt at a Solution

The only reasonable answer I can formulate is the fact that when 'h-bar' is zero, the momentum/its kinetic energy is greater than or equal to zero. However in classical physics the kinetic energy of an object can be zero (if its at rest), whereas in Quantum physics, using the Heisenberg Uncertainty principle above, it cannot be zero.

Any help?
