Coefficient of static friction: Experimental Measurement

 This is an experimental project where you are going to check some of the conceps you learnt in Phisics: The inclined plane movement.

You will calculate the coefficient of friction between to surfaces using the mobile phone as your instrument to take measurements... sheet with the basics

Here you have three videos that explain the activity:

1st video: The basics about Physic concepts applied & the use of the phyphox mobile app

 

 2nd video: Exporting the data to exel, reading the data and understanding the information given

 

 3rd video: Calculating the coefficient with several experiments

Coefficient of kinetic friction: Experimental measurement

 Let`s analyse now the experiment and conclusions to measure the cofficient of friction when the object is already moving on an inclned plane.

Here you have a sheet that explains the basic physic fundaments to understand the activity and some videos that may help you analysing the data given by the phyphox application, using excel.

👀Watch this second video and learn how to use excel to analyse all the exported data by the app phyphox.

And how to do the final calculation using the tendence line values is shown is this video 👀:

Using the mobile like a Physics Laboratoty: Angles

 This is our new project!!

You are going to use your mobile phone sensors to take measurements and do Physics calculations.

To do so you will use the android app phyphox. 

Let us start with trigonometry measurements: activity phyphox01

Here you have the way to calculate the angle using your mobile accelerometer:  sheet1

1. Install the app on your mobile
2. Take the measure of different angles
3. build an excel spreadsheet to do the calculations  (use the excel in office365 to work together with your partner by sharing the same document)
4. Organize the information on the spreadsheet so that to be printed 
5. Upload both xlsx and pdf 
6. Publish an article on your blog explaining the activity and results
