First of all a respectful greeting to all the academic and scientific community of @Hive.blog, we continue with our purpose of knowing a little more about the wonderful phenomenon of the center of gravity of a certain body, object or system of particles around us.

Introduction

Our optical systems are permanent witnesses of the great amount of phenomena that develop in our environment, of course, many of them we do not perceive, but others do, the truth is that they are part of our lives and our interest to learn from them, as anticipated in this opportunity we will continue structuring a particle system in order to put into practice the conceptualization of the center of gravity.

For this purpose, we will carry out a small practical experience that will continue to help us understand the phenomenon of the center of gravity and also with very simple materials available at home so that each of you can do it at home.

We continue to emphasize my dear friends that any object or body is constituted by any number of particles and they have their own weight and all these particular weights make up the total weight of the object or body, where there will be a resultant force imaginary locating a concentric point and that allows us to give balance to the whole system of particles.

Center of gravity of some objects or particle systems

This time it occurred to me to make a rectangular cardboard structure by making a cut at its base of approximately 45 ° in order to balance it with any other object that I have in my case which allows moving the center of gravity of the entire system of particles at the base of the rectangular cardboard structure, but before I can show you the step by step of the particle system that has occurred to me is necessary to know the materials used:

• A piece of cardboard of 30x35 approximately.
• 45° angle bracket.
• Scissors.
• Pencil.
• Stapler.
• A small file, screwdriver or any other object that provides stability to the cardboard structure.
• Silicone rod.

Having described the materials to be implemented, let's start visualizing the images that led me to the structuring of the particle system to be analyzed.

In the previous image you can see the piece of cardboard implemented for the realization of my rectangular structure as you can see in the following image.

After structuring this rectangle I proceeded to measure 45° from the base of my structure to cut as you can see in the following pictures.

Now let's try to place it on the surface to see if it stands up and logically it does it with the help of my hand otherwise it would fall down as you can see in the following picture.

I then proceeded to locate the approximate center of gravity of the rectangular cardboard structure using a cylindrical silicone rod and a balance-type technique until the structure is in equilibrium as you can see in the following image.

Once I have located the approximate center of gravity of the rectangular structure with the square, I could see that this point of gravity is outside the support base of the rectangular cardboard structure, so it is impossible for it to stand on its own, as you can see in the following image.

We proceed to make some holes in our cardboard structure where we will hook the other object that will form the particle system in order to balance the whole system.

By inserting in one of the holes our complementary object for the particle system we can notice how we have moved or found the center of gravity of the whole particle system and this concentric point of course is located inside the support base of the particle system as you can see.

In the following image you can see how I tried to insert the component object in each of the holes made, giving as successful those two holes that are closest to the center of gravity of the cardboard structure.

Conclusion

Everything that surrounds us is splendid and loaded with any type of phenomenon of which we are part, and in addition, we have learned and will continue to do so wherever we are, whether in our classrooms or outside of it, the truth is that science is part of our existence and will always be this way.

In this opportunity my dear friends we continue learning a little about the wonderful phenomenon of the center of gravity highlighting that with materials easily accessible in our homes and in this way we share with our children this essential knowledge of which we enjoy doing it.

Until another time my dear readers of @Hive.blog, especially the members of the great @stemsocial community, to whom I recommend to be part of this great project, because it highlights the excellent work of the academy and the wonderful work of the entire scientific field.

Note: All images are my own and worked in Power Point, and they were photographed with the camera of the Samsung Galaxy J2 Pro cell phone, and the animated gif was made with Photo Scape.
