(physics) A particle accelerator that uses plasma as the medium of the accelerating field instead of a vacuum, to obtain a larger accelerating gradient.

(physics) A method for accelerating electrically charged particles with a large-amplitude electron plasma wave.

The force which causes accelerated motion.

(law) a provision in a contract that makes all obligations to be performed under the contract due immediately upon a specific occurrence, such as a breach

plural of acceleration clause

(physics) A four-vector that describes the change in a particle's four-velocity over time

(computing) A keyboard shortcut.

plural of particle accelerator

plural of accelerator key

(physics) The acceleration felt by an object, as opposed to the coordinate acceleration. For example the acceleration of an object at the surface of the Earth is 9.81 m/s² upwards, but has no coordinate acceleration. The proper acceleration of an object is Lorentz invariant.
