In this article, we’ll be talking all about acceleration: what it is and how to calculate it. Acceleration is the rate of change of velocity. At any point on a trajectory, the magnitude of the acceleration is given by the rate of change of velocity in both magnitude and direction at that point.

The discovery of the Higgs boson will complete the standard model — but it could also point the way to a deeper understanding, says Gordon Kane.
