Physics in the Dance

Marjorie Carrión Rodríguez

In the life the humans have different passions and interests. These interests may vary depending on the possible skills in each person. It is incredible that many of us do not realize that our whole world and everything we do is possible for many factors but one of them is very important.  For example, the Chemical and others things but I believe the most important is Physics. We begin by defining, what is the physics?  Physics is a natural science that studies the properties of space, time, matter and energy and their interactions.  Now we know its meaning and we can think if any activity that we do every day and is very passionate have influence of physics.  For my part one of the things I like very much is the dance.  Since I have use of reason I dance and now I realize that not only we need ability to dance, there many factors that affect it and this factors not depend of me for example the science of physics.

Given that physics studies many aspects of the world, we know that some factors that affect the dance are the laws of gravity, momentum and energy. The same influence on the subtleties of balance, the techniques of leaps and pirouettes, and the impressive lifts and turns executed by the partners and body dimensions in the art of ballet. We begin by gravity which is very important if not the principal and it is responsible to keep the dancers in balance. The gravity effects depend of gravity center. The gravity center is the point where reflects all the forces applied to the body of the dancer. The forces are more than one. The weight combined with the movements and the force exerted by the surface of the floor to the dancer. At the same time the gravity influence  the jumps and spins, controlling the speed to controlling the configuration of the body and rotational inertia, the generation of adequate forces on the ground to initiate movements, controlling the time and height of the jumps.

In the dance the kinetic energy is important to study the movement of the dancers. The dancers make work to do their movement.  That movement can be done with coordination and perfection that also needs to develop a specific acceleration starting from rest and integrating the couple that is an additional source of force that combined with the gravity and soil. 

Something that calls my attention was an engineer that use pieces of bricks and for physical process caused an explosion called The Physics of Dance. This engineer make possible that the pieces of bricks dance a beautiful song. For me the fact of know that the physics can do things that a lot of us thought are impossible to do is something incredible and surprising. Personally the dance is one of the things that make me happy and comfortable, I love the dance and today I understand that physics is very important in the developing dance.
