50 Hertz:Also written as 50 Hz or 50Hz. This is the frequency at which mains electricity in Ireland is delivered at. We know that in an AC circuit, rather than flow constantly in one direction, the electrons move rapidly back and forth. The rate at which these electrons move back and forth is referred to as the frequency of the supply. In Ireland, the mains AC supply has a frequency of 50 Hz. In other words, the electrons in our homes move back and forth in the wires 50 times every second when a circuit is closed. |

A4 Lever Arch Folder:
It is important to get into the habit of writing up your notes on a regular basis. To that end, you are supplied with a spiral notebook and black and red pens. During induction, you will also purchase a geometry set and a pack of markers. |
A4 Refill Pad:
In order to help you do this, you will be issued, free of charge, a spiral notebook and an A4 refill pad. As you fill these pads and notebooks, you will be given new replacement items, also free of charge. | |

AAE:Advanced Automotive Engineer. This is a qualification awarded by the Institute of the Motor Industry. |
ABS:Anti blockier system, or anti-lock braking system, an electronically controlled system that senses the relative speeds of road wheels in order to determine whether braking wheels have locked up and began to skid. If they have, the system overrides the braking effort supplied by the driver, and frees the brakes until the wheel begins to turn again (stop skidding). The system is informed by speed sensors at the wheels. These same sensors can be used to feed into a traction control system. | |

Acceleration:Acceleration is simply a change in speed. Acceleration can be positive - an object speeds up, or it can be negative - an object slows down. The kind of acceleration we all experience every day is the acceleration produced by gravity - 9.81m/s2, referred to as 'g' in engineering calculations. For example, in order to calculate the weight of an object, we multiply its mass by the acceleration produced by gravity: W=m.g
