Initially they all had pendulums and gears.
How does a wall clock work.
A rubber ball when held at a certain height above the ground has a certain amount of potential energy which rapidly converts to kinetic energy after it is dropped.
The energy is usually stored in a weight or spring.
Timepiece image gallery clocks come in many different forms from quartz watches to atomic clocks.
One turn of the nut should impact the clock by about two minutes in a 24 hour period.
Take a peek under the hood and learn what makes each kind tick.
Perhaps the most important component inside a mechanical clock is known as the escapement.
In summary then the key parts of a pendulum clock are.
Here are some of the most common oscillators.
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.
All machines including timekeepers need energy to work.
See more pictures of timepieces.
As we will see in a moment the clock uses that potential energy as the weight falls to drive the clock s mechanism.
Winding your clock actually winds an internal mainspring.
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.
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.
When the mainspring slowly unwinds it puts a series of parts in motion which results in the turning of the gears.
Physical harmonic oscillator is the key component of every modern clock.
This is the same principle on which every pendulum clock on earth works.
A summary of how clocks work.
A dial and hands that indicate the time.
Clocks are one of the very first complex machines created by humans.
Winding the clock raises the weight back up storing more potential energy to power the mechanism.
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.
To slow the clock down the pendulum bob should be lowered by turning the nut to the left.
