Question

can you observe the energy states of ball of mass 100g moving in a box of length 1 m

Answer 1

Answer:

Probably frictional and gravitational energy

Answer 2

Answer:

No, we cannot observe the energy states.

Explanation:

No! The ground state energy of the particle in the one-dimensional box is

$e = {h}^{2} \div (8m {a}^{2} )$

where

h=6.6x10−34 joule seconds is Planck's constant,

m is the mass, and a is the length of the particle. box.

The energy is kinetic energy.

$e = 0.5m {v}^{2}$

So substituting the values we get numerical particle velocity about 1.28x10−17m/s.

The age of the universe is about 4x1017 seconds, so particles travel about 10−15 meters during the age of the universe.

This distance is the size of a proton.

So we cannot observe the energy states.
