Constant acceleration, the term in consideration here, assumes that the rate of change of velocity over a period of time is constant . In other words, if you were in a bus that was in a state of constant acceleration, we would say that the bus was either speeding up or slowing down at a steady, constant rate. 1 Introduction Linear accelerators for electrons are important tools for high-energy physics research because they circumvent the problems of synchrotron radiation that limit beam energy in circular accelerators.
