A pendulum with a length of 1 meter has a period of about 2 seconds (so it takes about 1 second to swing across an arc). This means that there is a relationship between the gravitational field ( g ...
A pendulum's period is related to its length, but the relationship is not linear. A pendulum that is twice as long as another pendulum does not simply have a period that is also twice as long.
Further, I said that the period of a pendulum with a length of 1 meter is 2 seconds. This would mean that pi squared would be g (the gravitational field in N/kg) - which it is.
Huygens solved the essential problem in Galileo’s concept by “making the period of a pendulum truly constant by devising a pivot that caused the suspended body, or bob, to swing along the arc of a ...
The 18th-century horologist John Harrison claimed that he could make the world's most accurate pendulum clock, but his methods were scorned for hundreds of years—until someone proved him right.
