The initial energy required is usually called an activation barrier.

A rocket does not have enough initial energy to allow stabilization this way.

The initial high energy to start these reactions came from widely scattered pebbles of special living crystal.

"As this works its way through the courts, it loses some of its initial energy."

Was this because the initial energy was difficult to maintain?

They must gain their initial energy of motion from a launch process.

The range depends upon the type of particle, its initial energy, and the material it traverses.

These people crave sugar, but they also experience the crash that follows the initial energy high.

It further lets only those electrons pass which have the chosen initial energy.

The initial energy has dissipated and all too often we are back to 'business as usual'.
