I could see where the other energy was going sideways and then vanishing in the direction that Aahz had pointed.

But energies and rubles that might have been invested in Russia vanished into desolate terrain inhabited by hostile peoples.

(The corresponding energy vanishes in the case of massless particles.)

The bustle and energy, all the gusto that was so much a part of her, had vanished, and she moved with a leaden, mechanical stride.

Then the energies themselves vanished.

Again the electrical energy vanished.

However, in the classical interpretation, it is zero and the thermal energy of matter vanishes.

The game was only five minutes old, but the energy inside the ballpark was vanishing.

The energy that has been emanating off him like sparks from a laboratory power source has vanished, as if someone had cut the switch.

Even when the mage-storms had caused such disruptions in magic, the energy had never vanished, it just hadn't worked or felt quite the same.
