Time, Clocks and Gears

[@mercenaryomega1]

very well put together examples of how gears are used in clocks. I will definitely be passing along this video to my homeschool friends and family. Keep up the excellent videos!

Good question - the escapement mechanism is designed to "kick" the pendulum on each stroke. The force to do this comes from the suspended weight.

Thank you for all these videos. I think, if you would get enough advertising, you would have like a million viewers.

Amazing how people have created technology such as these clocks over the years. Still, I find this video quite interesting how a clock works. You should make a video about how digital clocks work... You don't 'ave to, just suggesting... Keep up the good work! Invun

IF there was no friction on the pendulum, the weight would be useless. but since there is, the kinetic energy by the weight falling replaces the EXACT amount of force that was lost to friction. get it now?

Great Video. We also restore and work on clock towers and bell towers. Smith's Bell and Clock Service, Inc.

@blueshift314 Clocks are wound regularly to ensure the weights never reach the ground. Most clocks run for a week with a reserve of one day. (so-called 8 day clock) The clock weights can then be wound up again on a specific day of the week. Some clocks only run for 30 hours. Requiring daily rewinding with a few hours reserve. It is amazing to think that some clocks have been wound laboriously for centuries without a break. (except for occasional repairs)

Good work! Jordan, at the Canadian Clock Museum

what happens when the weight touches the ground? wouldnt the clock stop? how do they fix this problem

[@ChrisOrillia]

how often do you have to rewind a normal house clock?

[@DeaconSwayne]

great video, thanks.

[@Doggieman1111]

nice documentary thanks

[@ObjectsInMotion]

i love this video!

[@ElPolloGullefjun]

wow, can everyone see the cubes in the center of the clock?6:02

[@peacenik]

neat stuff. hooray for science!

[@Kivencito]

AWESOME

[@spanel36]

rewind the cord

[@jsb0321]

you wind it back up.
