pendulum help ! (1 Viewer)

[miss_a]

would anyone know where to find a scaffold for justification responses, or how to answer this question "Justify the appropriateness of your investigation procedure the investigation was to use pendulum motion to determine the value of g

also, can someone please help me point out if there are any other improvements that could be made to the investigation (including computer assisted technology) aside from
-using data loggers and motion sensors to eliminate random error resulting from human reaction times when timing, parallax and accuracy of instruments, to improve accuracy
-replicating over greater range experiment to improve reliability
-replacing worn or weak instruments (including the string)

thanks ahead to all who help

When justifying experiments you should refer to accuracy, validity, reliability. For example, for small angles of swing the pendulum period formula is a suitable approximation and the technique is valid to deduce period. And as you have mentioned it is easy to increase reliability of results by repeating experiment.
