What keeps the pendulum swinging

Types and Styles of Antique British Clocks. Hang the clock on the screw. I know nothing of these clocks, and unsure if they have to be wound like a watch. To confirm that your cuckoo clock is operating correctly advance the minute hand clockwise to the nearest hour or half hour and listen for the cuckoo and music for musical clocks. Since in theory, at least a pendulum of a certain length always takes the same amount of time to swing back and forth, the pendulum is what keeps the clock to time.

Most curricular materials in TeachEngineering are hierarchically organized; i. Some activities or lessons, however, were developed to stand alone, and hence, they might not conform to this strict hierarchy. Related Curriculum shows how the document you are currently viewing fits into this hierarchy of curricular materials. How do pendulums work? Pendulums are used in many engineered objects, such as clocks, metronomes, amusement park rides and earthquake seismometers. In addition, engineers know that understanding the physics of how pendulums behave is an important step towards understanding motion, gravity, inertia and centripetal force.

Swinging with a Pendulum

Home Videos Science Uncover the forces of potential energy, kinetic energy, and friction behind a grandfather clock's pendulum. Article media libraries that feature this video: Kinetic energy , Mechanical energy , Pendulum , Potential energy. NARRATOR: A simple pendulum can be made by attaching a bob or weight to one end of a light rod and then suspending the rod from the opposite end, so that it can swing freely and evenly from side to side. An everyday example of a pendulum can be seen in a grandfather clock. The pendulum controls the movement of the parts inside the clock.

A pendulum clock is a clock that uses a pendulum , a swinging weight, as its timekeeping element. The advantage of a pendulum for timekeeping is that it is a harmonic oscillator : It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates. From its invention in by Christiaan Huygens , inspired by Galileo Galilei, until the s, the pendulum clock was the world's most precise timekeeper, accounting for its widespread use. Moreover, their greater accuracy allowed for the faster pace of life which was necessary for the Industrial Revolution.
