lets us know how much time we've wasted doing nothing and that were late for whatever it was we meant to do today

This is really a history question. Today, of course, they have electronic clocks, and they wouldn't qualify as being mechanical. So to get the answer, we must go back in history.

Probably the first clocks, going back to ancient times, were sundials. But sundials have no moving parts, so they don't qualify as mechanical either.

Also, they had hourglasses, like egg timers. But they weren't really clocks, because they didn't say what time it is.

Mechanical clocks were first invented in the Middle Ages, maybe around the 13th century or a little later. They were in clock towers, and all they could measure were the hours. No minutes in the beginning. These early clocks would be in the center of towns in Europe, and could be used, for example, for people to know when town meetings or church services were scheduled to begin.

Galileo did a lot of work with pendulums, and pendulums are very good at keeping time. There were many improvements to pendulum clocks, and soon enough, wealthy people could have a pendulum clock in their home. Again, these clocks could be used for scheduling events.

The big breakthrough with clocks had to do with seafaring, especially when ships were sailing out of sight of land. Sailors could always find their latitude (north-south), but they could never find their longitude (east-west). (That's why Columbus never knew where he was.)

Sometimes ships, sailing north or south, would be blown off course, and, not knowing where they were, they might hit some rocks and be shipwrecked.

This problem of finding longitude was solved by John Harrison, an English clockmaker, who invented a mechanical clock, around 1750, I think, that kept near-perfect time aboard a ship out in the open ocean.

This was very difficult, because pendulums don't work when the ship is pitching up and down, and rolling side-to-side in the ocean.

Harrison's clock, called a "chronometer", made it possible to keep good time at sea. This, in turn, allowed sailors to know their longitude; so for the first time, they knew where they were. Mechanical clocks made this possible.

The next big use of mechanical clocks came with railroads in the 19th century. Until then, most people stayed near home, or if they traveled, they just rode horses. But with trains, people could ride from one town to another, and train schedules became important. To keep the trains on schedule, they used clocks (and they invented time zones too). Also, this meant that the time in one town and the time in a different town could be "synchronized".

And finally, during the Industrial Revolution, a lot of people went to work in factories. Some might work 8 to 5, others from 11 to 7, and so forth. Timekeeping in the Industrial Age was important, and many factories had steam whistles to signal the beginning or end of a work shift. Also, during this time, office workers were required to "clock in" and "clock out" when they arrived to or departed from work. If they were a few minutes late, they had their pay "docked".

Church bells rang on the hour. Schools started at a certain time, and classes started and ended according to the clock.

In the 19th and 20th centuries, people's lives became regulated, to a large degree, by the clock.

And until they invented the transistor, all these clocks were mechanical.

Here's the end of the story. Although I have an electric clock in the kitchen, a battery-operated clock in the bedroom, a fancy Seiko electronic wrist watch, and a quartz clock in my car, my two favorite clocks are a 50-year-old wind-up wrist watch and a weight-driven pendulum wall clock. Both of these are mechanical (no batteries, no electricity, no quartz crystals), and both go "tick-tock". They're easily my favorites.

Hope this helps with your science project.

It keeps us regulated.

Everything runs on a schedule.

As the early trains ran, when the United States was young, the people would get a schedule and they would not arrive on time because everyone had thier own time. So, they, the railroad invented time zones.

With the advent of the time piece, the World is syncronised.

I wish you well..

The mechanical clock made accurate navigation on the ocean possible. While it is possible to determine your latitude using the sun and stars, to determine your longitude, you need to know the exact time. The development of advanced mechanical clocks made this possible.
