Coefficient of kinetic friction: Experimental measurement

This is an experimental project to measure the cofficient of friction when the object is already moving on an inclned plane.

First, we used the Phyphox app to obtain the data, then exporting the data to excel then we calculated using the formulas.

Results:

Coefficient of static friction: Experimental Measurement

This is an experimental project to calculate the coefficient of friction between two surfaces using a mobile phone as a measuring instrument.

First, we used the Phyphox app to obtain the data, then exporting the data to excel , and finally, calculated the coefficient through several experiments. We also calculated the average.

Results:

Measuring angles with the mobile accelerometer

Using the mobile like a Physics Laboratoty: Angles

The task consisted of calculating and measuring thirteen angles using the Phypox mobile app.

To do this, we placed the mobile phone in different positions and, with the help of the app, collected the necessary information to perform the requested operations and calculate the arc.

Then, we compared the resulting angle with the actual angle initially measured and calculated the percentage error.

Results:

Graph of the Cosine Function

The first activity involves performing some calculations and creating the graph of the cosine function in Excel: y(t)= A cos (wt + φ0)

Steps:

- First, I provided values for time (t) and then multiplied it by W to obtain wt. I added φ0 to the result.

- Then, I calculated the radians and cosine of the angle obtained.

- Finally, I multiplied the cosine value obtained by the A value and created the graph with these numbers.

The graph obtained is:

Final project: Mosaic of portraits

Digital image. Final project

The final project is a mosaic with photos that we have made in class, then I have put some effects and details.

Mosaic of photos with colour effects

Create a mosaic of several photos using Gimp.

Original pictures

Final picture

Steps:

- First I have chosen three photos and I have applied different filters and effects.

- Finally, I have put them all together in a mosaic and I have put my name.
