Lab - Finding the Acceleration of Gravity
Name __Michelle Balderrama 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 can help you learn the following:
how to independently collect data using a modern device
how to reject non accurate data
how to analyze data using a spreadsheet.
Introduction
This Lab uses your phone (or an iPad) and an App called Phyphox. In this activity you will measure the acceleration of gravity “
g
” with an App on the phone.
If you do not have a smartphone, maybe you may borrow one from a friend or a family member. If you have trouble finding a smartphone to use, please let your instructor know and they will find a solution.
You will report your data in a spreadsheet in Microsoft Excel. Make sure to save this lab worksheet and submit it together with the Microsoft Excel file as your report.
Video description of the App and How to Use it
Activity 1.
Download the App Phyphox
on your phone. The app was created
by the Institute of physics at the Aachen University in Germany.
2.
Open the App and select the experiment Acceleration (without g).
Note from the App developer The experiment “Acceleration (without g)” gives the raw data from the phone’s accelerometer. There is a distinction between “Acceleration with g” and “Acceleration (without g)”. The sensor in your phone actually measures a force on a sample mass, which includes the contribution from gravitational acceleration. Therefore, this sensor will report the earth’s acceleration of 9.81 m/s² (a.k.a acceleration of gravity near/on the Page 1 of 4
NOL PHY 201
surface of the earth) while the phone is resting (which is what we call “Acceleration with g”). In contrast, the physical acceleration is zero when the phone is resting (or moving at a constant speed), so most phones offer a virtual sensor which subtracts the constant acceleration (usually by taking into account the data from other sensors as well). This is what we call “Acceleration (without g)” and it will actually report an acceleration of zero while the phone is not accelerated.
3.
Select the tab "Absolute
" acceleration
.
4.
Click play
, and drop the phone from a certain height. Around 20 cm is good. Be careful to drop it on a soft surface like a bed, a pillow, or a sweater!
5.
Stop
the data collection.
6.
Use the "Pan and zoom
" tool on the bottom of the screen to zoom the image. Find the interval of time of free fall where your data are about alligned on a flat horizontal line. Please see the image below.
7.
Use the "Pick data" tool on the bottom of the screen to select one data in the free
fall region. Report it on the table below. Be mindful of significant digits.
8.
Repeat the experiment 10 times.
9.
For each trial, take a screenshot of your phone screen showing the data-point you selected. Report all ten screenshots here. [Screenshots]

A penguin starts from rest and accelerates across the snow at a constant rate until he hits
the ice, as depicted in the figure below. He then throws himself down and begins to slide along
on the frictionless ice. He then goes over the edge into an ice gully and slides up a vertical ice
cliff on the other side.

a) Draw a curved line on your paper that represents the shape of the snow and ice
(you don't have to draw the penguins). Add points to your drawing that are like the
labeled points above. Along your line, draw an arrow to represent the penguin's veloc-
ity at each of the labeled points, including roughly scaling the lengths of the velocity
vectors to represent the penguin's speed at each point. If it is zero at any point then
write "v = 0" by the point.

labeled points. If the acceleration is zero at…
