Moreover, the simulation only offers discrete input increments for distance and mass, whereas +the scale (particularly for distance) is free to move at any point in the screen. Hence, the distance intervals may be slightly inaccurate +as they depend on teh accurate placing of the two objects based on teh scale. Offering continuos distance inputs would offer a slight improvement. +Due to the relatively high number of trials conducted, these errors are relatively negligible in finding proportionalities; however, they can significantly impact the calculation of $G$. +Hence, $G$ was calculated using the default values for distance, ensuring that there would be no innacuracy of the data point. \end{document}
