A device that accelerates electrically charged particles to extremely high speeds, for the purpose of inducing high energy reactions or producing high energy radiation.

(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

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

(mechanics) Motion with a continually increasing velocity.

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

The force which causes accelerated motion.

(classical mechanics) The rate of change of angular velocity, often represented by α.

(physics) The acceleration of freely falling bodies under the influence of terrestrial gravity; 980.665 cm/sec², denoted g.

(economics) A theory in economics that states that an increase or decrease in income induces a corresponding but magnified change in investment.

(astronomy, astrophysics) A theory that describes and seeks to explain the seemingly increasing rate of the expansion of the universe.
