Investigating circular motion

INVESTIGATING CIRCULAR MOTION 11/3/04 AIM To examine some of the factors affecting the motion of an object undergoing uniform circular motion, and then to determine the quantitative relationship between the variables of force, velocity and radius.

…-gram graph was found to be approx 26 and gradient of the 100-gram graph was found to be double approx 53. slight discrepancies were found and these were attributed to human errors such as measuring. However the effects of these errors were minimised by taking a line of best fit eventually giving a straight-line graph representing v" is proportional to r.
