The time for one complete cycle, a left swing and a right swing, is called the period. The period depends on the length of the pendulum, and also to a slight degree on the amplitude, the width of the pendulum's swing.he period of swing of a simple gravity pendulum depends on its length, the local strength of gravity, and to a small extent on the maximum angle that the pendulum swings away from vertical, Î¸0, called the amplitude.
Compulsory elementary schooling was formally introduced in Sweden in 1842. A process of reform, destined to take many years, began in the 1940's with the aim of expanding compulsory schooling.
Compulsory military training was brought back in 1951 by the Liberal government as the National Service Scheme. The scheme was criticised as being irrelevant to modern defence needs, and for being a drain on the Regular Army's finances and manpower. In 1959 the scheme was abolished.
