Running Head: CIRCULAR MOTION 1 Circular Motion Student’s Name Institutional Affiliation CIRCULAR MOTION 2 Abstract This experiment explores the theory behind circular motion where it provides a practical understanding why objects move in a certain way. In addition, it illustrates how circular motion apply in real-world and acquits knowledge and experience on free-body diagrams. Introduction Circular motion involves the process of an object moving in a circular path. The movement can be uniform, in constant angular rate of rotation at constant speed, or non-uniform with varying rates of rotation. In this experiment, washers and fishing line will be used to demonstrate the effect of circular motion. Different radius of fishing lines are used to rotate washers for 15 rotations and time recorded for each radius. Materials 5 washers Fishing line ruler Metal tube Stop watch Scissors Permanent marker Methods i. A fishing line was threaded through the metal tube ii. Two washers were connected to the ends of the fishing line allowing a radius of 0.25m for rotation. iii. The tube was rotated for 15 full circles and time taken to rotate 15 rotations recorded. iv. Step ii) and iii) were repeated for the 0.40m and 0.15m radius fishing line Results CIRCULAR MOTION 3 Radius (meters) Time for 15 revs Period (sec) Theoretical Period (sec)* 0.25m 5.48 sec 0.365sec 0.501sec 0.40m 6.68sec 0.445sec 0.634sec 0.15m 4.40sec 0.293sec 0.388sec Questions 1 C ...
