HI
HERE IS THE ANSWER
AIM: TO SHOW THE CONSTANCY OF THE TIME PERIOD OF PENDULUM .
MATERIALS: A STRING , A SMALL STONE , A HANDLE OR DOORKNOB , AND A STOPWATCH .
METHOD:
STEP:1 TAKE A STRING OF LENGTH ABOUT 30 cm . TIE THE STONE TO ONE END . TIE THE OTHER END OF THE STRING TO A HANDLE OR DOORKNOB.
STEP: 2 DISPLACE THE STONE SLIGHTLY AND LET IT OSCILLATE . MAKE SURE OSCILLATES FREELY AND DOES NOT RUB AGAINST ANY OTHER OBJECT .
STEP:3 USE THE STOPWATCH AND NOTE THE TIME TAKEN BY THE STONE TO COMPLETE TEN OSCILLATION. [TAKE ANY ONE POINT , THE EXTREME POSITION IN THE OSCILLATION OR THE MEAN POSITION OF THE STONE AND COUNT THE NUMBER OF TIMES THE STONE CROSSES THIS POINT , IN THE SAME DIRECTION].
STEP :4 DIVIDE THE TIME TAKEN FOR TEN OSCILLATIONS BY 10. THIS GIVES TIME PERIOD OF THE PENDULUM .
STEP :5 REPEAT THE EXPERIMENT MANY TIMES WITHOUT CHANGING THE ARRANGEMENT . COMPARE THE VALUE OF THE TIME PERIODS OBTAINED.
