Let me start with a graph. This shows the horizontal acceleration of the pod as a function of time. Here the pod accelerates at 9.8 m/s 2 for 2.6 minutes and then travels at a constant speed.

The velocity time graphs give all three variables for motion–velocity which can be read off at any time. Area is displacement and gradient is acceleration.

A negative gradient shows the rate of “slowing down” or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The ...

As one of the leads, Changwoo Min, tells The Next Platform, even though terascale graph processing is no longer unheard of, finding ways to make it efficient and high performance is where the real ...
