It would be exceptionally difficult to design a battery and motor that together give exactly one rotation per second or per minute (to give good time). Instead a known constant output of a given motor and a given battery are used as a base point from which the speed must be geared towards your goal speed. Cogs, or toothed wheels, are used to take a fixed speed source (such as an electrical motor in a watch) and vary the output speed to the exactly desired speed. The teeth are used to give good traction between any two wheels touching each other, otherwise small variances in temperature etc night allow slippage between different sized wheels within the clock. The ability of cogs to vary speed results from the differences in circumference as they turn each other. By careful calculation any rotational speed can be geared up or down by neighbouring cogs. This is very similar to your bicycle and if you have access to a "spirograph" set you would be able to enjoy seeing the variable relationships between different cogs in action

Does the time clock stops when QB gets sack?
No it doesn't. After a sack, the clock continues to run like it does on a rushing play.
Who invented cogs?
Cogs were first mentioned in 948 AD, near Amsterdam in Muiden. They were influence by the Norse Knarr, which was a trade vessel in northern Europe, that used a steering ore.
Why do baseball players run the bases counter clock wise?
because most people are right handed and when they hit the ball the run straight to first base...if you ran toward third base, you would have to turn backwards!!
What is the past tense of clock?
The past tense of clock is clocked.
Which clock is bigger than the big ben?
Yes there is a clock bigger than the big ben.The mecca clock in saudi arabia.Big ben is only 96.3 metres (316 feet) and the mecca clock is 577 metres.However the mecca clock is not as wide in breadth.
