Centripetal Force Conclusion

Abstract

According to Khan Academy, Centripetal force “is a net force that acts on an object to keep it moving along a circular path.” According to this article, “any object traveling along a circular path of radius rrr with velocity vvv experiences an acceleration directed toward the center of its path,” In this experiment, the students used a centripetal force apparatus composed of string, a pen tube, a weight, and paperclip to determine the fundamentals concepts. Through repetitive trials, the students were able to see how centripetal force varies inversely to the radius and directly to the square of the velocity.

Introduction

A common experiment that is conducted to better understand the concepts of centripetal force is composed of

Conclusion and Generalization

In conclusion, the students were able to determine the fundamental concepts of centripetal acceleration. Like as mentioned above, how the centripetal forced varies inversely to the radius and varies directly to the square of the velocity. In addition to that, the students must also understand thar the tension (or the weight) serves as the balancing forced needed to keep the stopper moving in a circular path. By doing this experiment, they were able to further understand the basis of the formula of centripetal acceleration. Furthermore, knowing how the formula works will help in conceptualizing the problems.

Evaluation

1. What happened to the time that it takes the object to complete one revolution (period) as the radius of the revolution is increased? How is the period related to the radius?

-As the radius increases, the time it takes the object to complete one period also increases. The square of the period is directly proportional to the radius.

2, Did the balancing force equal the centripetal force? Do you consider them equal or not equal? Why or why

Like as mentioned above, how the centripetal forced varies inversely to the radius and varies directly to the square of the velocity. In addition to that, the students must also understand thar the tension (or the weight) serves as the balancing forced needed to keep the stopper moving in a circular path. By doing this experiment, they were able to further understand the basis of the formula of centripetal acceleration. Furthermore, knowing how the formula works will help in conceptualizing the problems.
