Circular Motion Experiment
February 18, 2020
Year 10 students at Assumption College English Program study the motion of an object travelling in a circle. If the object maintains constant speed it is said to be undergoing uniform circular motion. In this case, the students calculated the centripetal force by measuring the radius of the circle and the period of the object. This centripetal force was then compared to that of the weight force of the washers (which were providing the tension in the string). Ideally, these forces should be equal.
Students assessed the sources of error which might contribute to these two forces not being equal. They then suggested improvements to the experimental technique which might reduce errors.
