By providing constant frequency movement clock s mechanisms can capture those oscillations and transform them into precisely timed series of pulses that show us exact passage of time.
How does a wall clock work.
A dial and hands that indicate the time.
The energy is usually stored in a weight or spring.
Atomic clocks are designed to measure the precise length of a second the base unit of modern timekeeping the international system of units si defines the second as the time it takes a caesium 133 atom in a precisely defined state to oscillate exactly.
Clocks are one of the very first complex machines created by humans.
Here are some of the most common oscillators.
Winding the clock raises the weight back up storing more potential energy to power the mechanism.
In summary then the key parts of a pendulum clock are.
Take a peek under the hood and learn what makes each kind tick.
When the mainspring slowly unwinds it puts a series of parts in motion which results in the turning of the gears.
That gives the weight potential energy in the earth s gravitational field.
When you wind a weight driven clock you pull on a cord that lifts the weight.
To speed the clock up the pendulum bob should be raised up by turning the nut to the right.
Initially they all had pendulums and gears.
All machines including timekeepers need energy to work.
To slow the clock down the pendulum bob should be lowered by turning the nut to the left.
One turn of the nut should impact the clock by about two minutes in a 24 hour period.
This is the same principle on which every pendulum clock on earth works.
A weight that stores potential energy and releases it to the clock mechanism as it falls very gradually over the course of a day or several days if you re lucky.
Winding your clock actually winds an internal mainspring.
Caesium clocks in braunschweig germany.
As we will see in a moment the clock uses that potential energy as the weight falls to drive the clock s mechanism.
See more pictures of timepieces.
When it is wound energy is transferred from our muscles and into the driving weight as it moves up against the force of gravity or the mainspring as it tightens up.
A summary of how clocks work.
Physical harmonic oscillator is the key component of every modern clock.
Timepiece image gallery clocks come in many different forms from quartz watches to atomic clocks.
