- n. One who or that which accelerates; a hastener.
- n. A device in a motor-car by which the operator may render inoperative the speed governor of the motor. If the governor is of the centrifugal type, as the speed increases the balls or weights fly outward against the action of a spring. The accelerator increases the tension of the spring or draws the balls inward directly, so that the governor ceases to act to close the throttle or regulate speed as the motor increases its number of revolutions above the limit set by the normal tension of the springs.

Sorry, no etymologies found.
Here's a hint, the accelerator is the bigger peddle by ones right foot.
But part of what's helped him put his foot on the accelerator is the acquisition of CC Sabathia after he was traded to the Brewers.
There are non-obvious scenarios where you cannot tell whether your accelerator is sticking (such as the hill example).
Secondarily, where feasible, adding software to cars to ensure the brake can overcome the accelerator is cheap and a good idea.
Specifically, drivers are erroneously taught to shift into neutral if their accelerator is sticking.
Hey Walt, 48 grain accelerator $UCK $$$ I'll take a Hornady 130 grain in a 30-06 any day for critters and deer!!
The first Essay (Nature 455, 174 – 175; 11 September 2008), published to coincide with this week'sattempt to circulate a beam through the world's most powerful particle accelerator, is "Paris 1951: The birth of CERN", in which François de Rose, whochaired the meeting that founded Europe's premier facility for experimental nuclear and particle research, relives the five days of drama that changed the world of physics.
I should stress this disclaimer; every time a new particle accelerator is being built, some very crazy and silly people object because they think it will create a black hole that will eat us all.
The basic idea behind a particle accelerator is exactly what it sounds like.
Because the engine provides a lot of torque, and most of its power in the RPM bands one typically drives in, the accelerator is responsive when you need it, and being a turbo powerplant, it is not as affected with regard to power and mileage as a normally aspirated engine would be.
