How do old clocks work?
A pendulum works by converting energy back and forth, a bit like a rollercoaster ride. When the bob is highest (furthest from the ground), it has maximum stored energy (potential energy). So as the bob swings (oscillates) back and forth, it repeatedly switches its energy back and forth between potential and kinetic.
What is the 7 8 rule?
Quarter hour rounding (15 minutes): This is sometimes called the 7/8 rule. The 15 minutes is split so it is 7 ½ minutes before the quarter hour to 7 ½ minutes after the quarter hour and all the punches are on 15 minute increments. So if an employee punches in between 7:53 and 8:07 it will record the punch as 8:00.
Do you get paid if you clock in early?

Why does a clock tick?
Mechanical clocks/watches that make a ticking sound normally do so because they have an escapement mechanism to help regulate the movements of the hands, that is, to keep time well. This mechanism works along with a pendulum, balance wheel, or similar device to keep the hands moving at the correct rate.
Why won’t the pendulum keep swinging?
Have you recently moved your clock? The reason a clock pendulum often stops swinging, after being moved, is because the clock case now leans at a slightly different angle then it did at its former location. Don’t worry about making your clock absolutely level with the floor and don’t use a level.
What is the 9 minute rule?
The 9-Minute Rule: Rooted in Neuroscience Brains get bored fast. Neuroscientists have proven that our brains have a built-in stopwatch that stops around 9-10 minutes. To command the attention of your customer, you must introduce a “brain-perking” change of pace.
What is the 7 min rule?
To give a specific case of the ‘7-minute rule’ in action, a company that charges in 15-minute increments has an employee that clocks out in the seventh minute of their final shift. If they work for the full seven minutes the company can round down. Anything above that is rounded up to the nearest increment.
What is the 7 minute rule?

Who made time?
