A centripetal apparatus was used to obtain the measured mass of the system of 224g and the mass of the load which was 55g. The uncertainty of the mass and radius were taken to be u{m}=.1g and u{r}=.1cm respectively. The radius was then measured from the center of the circular orbit to the second post at a start of 6cm radius. This distance was increased nine times from 6cm to 24cm. we used the Science Workshop to measure the angular velocity at each given radius. A graph was plotted for angular velocity squared against 1/ (mass*radius) and the slope is the centripetal force. The calculated force for centripetal force using the LINEST function resulted in 0.504N±0.015N which compares close to the force of the load which is 0.539N±0.001N.
