Mario Samuel Fernandez R. Fisica Fundamental Tercero Basico Pdf: A Book Review

Mario Samuel Fernandez R. Fisica Fundamental Tercero Basico Pdf is a book that covers the basic concepts of physics for third grade students in Spanish. The author, Mario Samuel Fernandez R., is a professor of physics at the Universidad Nacional de Colombia. The book aims to provide a clear and simple explanation of the physical phenomena that surround us, such as motion, force, energy, heat, sound, light, electricity and magnetism.

The book is divided into 12 chapters, each one with a theoretical introduction, examples, exercises and experiments that can be done at home or in the classroom. The book also includes a glossary of terms, a list of symbols and units, and an appendix with tables and formulas. The book is illustrated with colorful diagrams and photos that help the reader understand the concepts better.

The book is suitable for students who want to learn the fundamentals of physics in an easy and fun way. It can also be used by teachers who want to enrich their classes with practical activities and demonstrations. The book is available online as a PDF file that can be downloaded for free from various websites[^1^] [^2^] [^3^] [^4^].Here is a possible continuation of the article:

One of the experiments that the book proposes is to measure the speed of sound using a tuning fork and a water bottle. The procedure is as follows:

Fill a water bottle with some water and make a hole near the bottom.

Place the bottle on a table and let the water flow out of the hole into a container.

Strike a tuning fork with a rubber mallet and hold it near the mouth of the bottle.

Move the bottle up and down until you hear a loud sound that matches the frequency of the tuning fork.

Measure the height of the water level in the bottle when you hear the resonance.

Repeat the experiment with different tuning forks and record your data.

Use the formula v = 4fL to calculate the speed of sound, where v is the speed, f is the frequency of the tuning fork, and L is the length of the air column in the bottle.

Compare your results with the theoretical value of 343 m/s at room temperature.

This experiment demonstrates how sound waves can create resonance in a closed tube. It also shows how the speed of sound depends on the temperature and density of the medium.Here are a few more paragraphs for the article:

Another topic that the book covers is electricity and magnetism. The book explains how electric charges, currents, circuits, resistance, voltage, power and energy work. It also introduces the concepts of magnetic fields, forces, poles, compasses and electromagnets. The book shows how electricity and magnetism are related by the phenomenon of electromagnetic induction.

One of the experiments that the book suggests is to make a simple electric motor using a battery, a coil of wire, a magnet and some paper clips. The procedure is as follows:

Make a coil of wire by wrapping it around a cylindrical object, such as a marker or a pencil.

Leave some wire at both ends of the coil and bend them into loops.

Remove the insulation from one side of each loop using sandpaper or a knife.

Attach a paper clip to each loop and connect them to the terminals of a battery.

Place a magnet under the coil and balance it on the paper clips.

Give the coil a gentle push and observe what happens.

Try changing the direction of the battery or the magnet and see how it affects the rotation of the coil.

This experiment demonstrates how an electric current can create a magnetic field and how a magnetic field can exert a force on an electric current. It also shows how a simple electric motor works by converting electrical energy into mechanical energy. 66dfd1ed39
