Understanding Pendulum Period: A Math Problem Explained

Understanding the concept of a pendulum's period is crucial in many scientific fields, including physics and engineering. A period is defined as the time it takes for a pendulum to complete one full cycle, which is essentially one complete to-and-fro motion. In this article, we will break down and solve a specific math problem related to this concept. We will explore what it means when a pendulum completes exactly 24 cycles in 3 minutes, and then determine the period of the pendulum.

What is the Period of the Pendulum?

First, let's define the period of a pendulum. The period, denoted as T, is the amount of time it takes for the pendulum to complete one full cycle. This includes both the swing to the right and the swing back to the left. It is a fundamental parameter in the study of pendulums, and it can be calculated using basic arithmetic and logical reasoning.

The Given Problem

The problem states that a pendulum completes exactly 24 cycles in a span of 3 minutes. To find the period of the pendulum, we need to determine how much time it takes for it to complete one cycle. Let's break down the problem step by step.

Converting Time into Seconds

The first step in solving this problem is to convert the given time (3 minutes) into seconds, as the period is typically measured in seconds.

3 minutes 3 × 60 seconds

3 minutes 180 seconds

So, we now know that 3 minutes is equivalent to 180 seconds.

Calculating the Period

To find the period, we need to divide the total time by the number of cycles. In this case, we are given that the pendulum completes 24 cycles in 180 seconds. Thus, the period T can be calculated as follows:

Total time 180 seconds

Number of cycles 24

T Total time / Number of cycles T 180 seconds / 24 cycles T 7.5 seconds

Therefore, the period of the pendulum is 7.5 seconds. This means that each complete cycle of the pendulum, from one side to the other and back to the starting point, takes 7.5 seconds to complete.

Summary

Understanding the period of a pendulum is essential for various applications in science and engineering. In this article, we solved a specific problem where a pendulum completes 24 cycles in 3 minutes, and determined that the period is 7.5 seconds. By following the steps of converting minutes to seconds and dividing the total time by the number of cycles, we arrived at this solution.
