Question

why is the time for more than one period of pendulum measured?

Answer 1

Answer:

Mass does not effect the pendulum swing.The

longer the length of string,the farther the pendulum falls;and therefore ,the longer period,the back and forth swing of pendulum.The greater the amplitude ,or angle,th farther pendulum falls;and therefore,the longer period

Answer 2

Answer:Time period can be calculated for just one oscillation also but in labs we calculate for 10-20 oscillations just to be more accurate. We take mean of these oscillations time period. By doing this we can also eliminate human error(*we may start or stop the timer earlier or late this error can be overcome usin this method)
