Lab - Simple Pendulum
Part 1
Name Michelle Balderrama
This assignment is divided into two labs: Part 1 and Part 2. In this part, you will build a pendulum and measure its period of oscillation, reporting the data on a table. Keep all the material because you will use it again in the second part. Save all the files. Before starting, please scroll through the worksheet to check the page numbers and get all the information. Complete all activities before submitting the lab.
Each lab counts for 20 points and is about 1.42% of the total grade.
Lab Goals
This lab will help you learn the following:
How to perform an experiment independently
How to take measurements, obtain results, and interpret them correctly
How to estimate the accuracy of experimental results.
Equipment
1.
A small object with significant weight for its size (like a washer, nail, ring, bead, coin etc..) and a long string.
2.
A measuring tape (or ruler) and a watch. If you don't have a watch, you can use your smartphone to measure the passing time. You can also use your smartphone to take measurements of the length of the string.
3.
Scissors, a pencil and a scotch tape.
Introduction
A simple pendulum consists of an object with negligible size hanging on a string. When the object is deflected from its equilibrium, it swings (oscillates) back and forth. The time
for one complete cycle (oscillation) is called the period of oscillation, T
. For small angles
of deflection, the period of the simple pendulum is given by the following formula:

where L

on the y-axis and L
on the x-axis, it is possible to obtain the acceleration of gravity starting from the slope and applying basic algebra.
Preliminary Setup: Build a Pendulum 1.
Cut a string approximately 90 cm. Tie one end of the string to the bead and the other to the pencil.
2.
Tape the pencil onto a table or any other surface, so that the bead is hanging freely. This is your simple pendulum.

Plz give a short answer to these three questions
1- The spring is characterized by the spring constant, moreover, the force per displacement. How is the slope related to the spring constant ?
2- How is the last column in the Table 4 related to the spring constant ? What if we average the values of last column in Table 4? Explain your answers.
What is the meaning y-intercept ? Do you understand why it is always better use y=mx+b as opposed to y=mx in performing a curve fit ?

Use the following prompt for questions 1-2.
Alexandra and Sal are conducting an experiment to study pendulums. In their first experiment, Alexandra and
Sal changed the length of the pendulum and measured its period. In their second experiment, the mass of the
pendulum bob was varied, and period was measured.
1. Before running the experiments, Sal hypothesized that increasing the mass of the pendulum would
result in an increase in the pendulum's period. Was Sal correct?
A. Sal was correct because mass is the only variable that will affect the period of the pendulum.
B. Sal was correct because mass and length both affect the period of the pendulum.
C. Sal was incorrect because only the length of the pendulum will affect the period of the
pendulum.
D. Sal was incorrect because only the initial angle will affect the period of the pendulum.
