What are the parts of a pendulum clock?
The movements of all mechanical pendulum clocks have these five parts:
- A power source; either a weight on a cord or chain that turns a pulley or sprocket, or a mainspring.
- A gear train (wheel train) that steps up the speed of the power so that the pendulum can use it.
What is the small line on the clock?
The small hand on a clock that shows the hours. It goes once around the clock every 12 hours (half a day). (The large hand is the “minute hand” and it shows that it is 22 past the hour, so it is 22 past 8).
What does it mean if the minute hand is on 12?
Students learn that when telling time to the hour on an analog clock, the minute hand is on the 12 and the hour hand is on the hour. They say the hour first and then “o’clock”. For example, if the hour hand is on the 4 and the minute hand is on the 12, they say 4 o’clock.

What is mechanical clock?
The mechanical clock comprises an oscillating mechanism that marks the passing of time, and an escapement that counts its beats. … The mechanical clock, which derived from water clock, was born in medieval Europe. The first mechanical clocks were large devices made of iron.
How do clock parts work?
The energy is usually stored in a weight or spring. 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). This energy is released into the timekeeper as the weight drops or the mainspring unwinds.
