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

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

The force which causes accelerated motion.

(mechanics) Motion with a continually increasing velocity.

(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

soil erosion occurring at a rate much faster than soil horizons can be formed from the parent regolith.

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

(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.

plural of four-acceleration
