Question

state three factors that limits accuracy of this method of simple pendulum in the determination of 'g'​

Answer 1

During this experiment:

The fan should be switched off to prevent air resistanceThe stopwatch zero error should be noted and corrected

The angle of bob displacement should be small

Simple pendulum

The simple pendulum a system that moves in an oscillatory motion. It consist of a suspended mass on a string with length placed on a fixed support.

The acceleration due to gravity can be measured using a simple pendulum. During this experiment:

• The fan should be switched off to prevent air resistance
• The stopwatch zero error should be noted and corrected
• The angle of bob displacement should be small
