Clock is the best invention in the world! The history of clocks is very long. There are many different types of clocks over the years. The word ‘clock’ was first used in the 14th century. It comes from the word for bell in Latin (“clocca”). The very first timekeepers were natural clocks such as the sun‚ moon and stars. Ancient people used sticks and stones to find out the time around 3500 B.C. When it was between 3500 BCE and 1949‚ the inventors improved clocks‚ and became the clock that

A ‘clock’ is an instrument used to specify‚ record‚ and manage time. The word ‘clock’ comes from the French word “cloche” meaning bell‚ came into use when timekeepers were kept in bell towers in the Middle Ages. Historians do not who or when mankind “invented” a time-keeping device or a “clock”. Probably thousands of years ago when someone stuck a stick in the ground and saw a shadow of the sun move across the ground‚ known as the sundial. (Cummings‚ 1997-2012). After the Samarian culture

Water clocks‚ along with sundials‚ are likely to be the oldest time-measuring instruments‚ with the only exceptions being the vertical gnomon and the day-counting tally stick.[1] Where and when they were first invented is not known‚ and given their great antiquity it may never be. The bowl-shaped outflow is the simplest form of a water clock and is known to have existed in Babylon and in Egypt around the 16th century BC. Other regions of the world‚ including India and China‚ also have early evidence

The pendulum shows elastic collision and conserved momentum. In this set up‚ no momentum is actually lost. Ball 0 just transfers its momentum to stationary ball 1 which it collides with(head-on collision) so ball 0 is put to stop then ball 1 collides with ball 2 causing ball 1 to stop and transfer its momentum to ball 2 and so on until the momentum gets transferred to ball 4 then ball 3 collides with ball 2 and the cycle continues.

One Title: Determination of the acceleration due to gravity with a simple pendulum Introduction and Theory: A simple pendulum performs simple harmonic motion‚ i.e. its periodic motion is defined by an acceleration that is proportional to its displacement and directed towards the centre of motion. It can be shown that the period T of the swinging pendulum is proportional to the square root of the length l of the pendulum: T2= (4π2l)/g with T the period in seconds‚ l the length in meters

1.0 Introduction According to (Baillie et al.‚ p. 307; Palmer‚ p. 19) “A clock is an instrument used to indicate‚ keep‚ and co-ordinate time. The word clock is derived ultimately (via Dutch‚ Northern French‚ and Medieval Latin) from the Celtic words clagan and clocca meaning "bell". A silent instrument lacking such a mechanism has traditionally been known as a timepiece.” Design and accuracy of clocks have evolved along with progression of technology and industry and even though their main

Think of all the work that was put into making a Grandfathers clock. The definition of a Grandfather Clock is a clock in a tall freestanding wooden case‚ driven by weights. Grandfather Clocks have been a part of family legacies including my own for generations. My Grandfather clock is a “Ridgeway”. The Manufacturer is Ridgeway Clocks. They are the oldest
