Esto no ha cambiado respecto a la serie D. En los instrumentos cient\u00edficos, aunque cambien el dise\u00f1o o el fabricante, se establecen unas especificaciones comunes para que los resultados puedan compararse. Si cada carro tuviera una masa diferente, cuando observ\u00e1ramos que \u00abal aplicar la misma fuerza obtenemos aceleraciones distintas\u00bb, no sabr\u00edamos si la diferencia se debe a las caracter\u00edsticas de cada carro o a las propias leyes de la f\u00edsica. Puede parecer un detalle insignificante, pero establecer una masa est\u00e1ndar de 1 kg es una decisi\u00f3n muy importante desde el punto de vista cient\u00edfico.<\/p>\n<p>Y el nuevo F-1 se mueve con una suavidad sorprendente. Incluso al empujarlo lentamente, mostr\u00f3 un <strong>movimiento casi uniforme<\/strong>. Esta caracter\u00edstica lo convierte en un instrumento perfecto para experimentar de forma directa la llamada \u00abprimera ley del movimiento\u00bb, es decir, la ley de la inercia, que tantas veces vemos en el laboratorio escolar. Cuanto m\u00e1s conseguimos reducir el rozamiento, m\u00e1s claramente nos muestra el carro esa tendencia a \u00abseguir movi\u00e9ndose a la misma velocidad mientras no act\u00fae una fuerza sobre \u00e9l\u00bb. Lo grab\u00e9 en v\u00eddeo, as\u00ed que \u00a1no os perd\u00e1is lo suavemente que se mueve!<\/p>\n<p><iframe loading=\"lazy\" title=\"\u529b\u5b66\u53f0\u8ecaF-1\u3092\u8cb7\u3063\u3066\u307f\u305f\uff01\u30ca\u30ea\u30ab\u88fd\" width=\"1140\" height=\"641\" src=\"https:\/\/www.youtube.com\/embed\/KHjzATZRDuQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<h3>\u00a1Analicemos a fondo el F-1!<\/h3>\n<p>Tambi\u00e9n tiene un lugar espec\u00edfico para colocar la cinta de registro, un detalle muy bien pensado.

Hoy podemos medir la velocidad f\u00e1cilmente con sensores o aplicaciones, pero la idea de utilizar la frecuencia de la electricidad como una especie de \u00abmetr\u00f3nomo natural\u00bb para registrar el movimiento me parece sencilla y muy inteligente.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-40099\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/04\/0fa9587044d6b18389f9bae5f2605cbc.jpg\" alt=\"\" width=\"876\" height=\"480\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/04\/0fa9587044d6b18389f9bae5f2605cbc.jpg 876w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/04\/0fa9587044d6b18389f9bae5f2605cbc-300x164.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/04\/0fa9587044d6b18389f9bae5f2605cbc-768x421.jpg 768w\" sizes=\"auto, (max-width: 876px) 100vw, 876px\" \/><\/p>\n<p>Adem\u00e1s, incorpora otros detalles muy interesantes:<\/p>\n<p>\u30fbDispositivo para colocar la cinta del registrador de tiempo<br \/>\n\u30fbSaliente para accionar el muelle de rebote<br \/>\n\u30fbDispositivo de rebote<br \/>\n\u30fbSistema de uni\u00f3n (velcro)<br \/>\n\u30fbRelieves para apilar los carros<\/p>\n<p>Cada una de estas piezas tiene su propia funci\u00f3n. Por ejemplo, el <strong>muelle de rebote<\/strong> permite hacer experimentos en los que dos carros chocan y rebotan, para estudiar c\u00f3mo cambia la cantidad de movimiento antes y despu\u00e9s de la colisi\u00f3n. Por otro lado, el <strong>sistema de uni\u00f3n<\/strong> con velcro permite hacer justamente lo contrario: unir dos carros y hacer que se muevan juntos, para comprobar c\u00f3mo cambia el movimiento cuando aumenta la masa. Es fascinante que, incluso partiendo del mismo fen\u00f3meno de \u00abchocar\u00bb, las leyes f\u00edsicas que podemos observar sean completamente diferentes dependiendo de si los objetos rebotan o quedan unidos.<\/p>\n<p>La parte inferior tiene esta estructura. Los <strong>rodamientos<\/strong> est\u00e1n muy bien dise\u00f1ados y permiten que el carro se deslice suavemente. Un rodamiento funciona colocando peque\u00f1as bolas entre la rueda y el eje, transformando el \u00abrozamiento por deslizamiento\u00bb, en el que dos superficies se frotan entre s\u00ed, en \u00abrozamiento de rodadura\u00bb, en el que las bolas ruedan. Como el rozamiento de rodadura es mucho menor que el rozamiento por deslizamiento, el carro puede acercarse mucho m\u00e1s al movimiento ideal sin rozamiento. Detr\u00e1s del movimiento tan suave del carro se esconden, por tanto, peque\u00f1os pero ingeniosos detalles tecnol\u00f3gicos.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-40097\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/04\/7c72b6b957109e063ffe5efe1a1b4673.jpg\" alt=\"\" width=\"1096\" height=\"606\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/04\/7c72b6b957109e063ffe5efe1a1b4673.jpg 1096w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/04\/7c72b6b957109e063ffe5efe1a1b4673-300x166.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/04\/7c72b6b957109e063ffe5efe1a1b4673-1024x566.jpg 1024w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2022\/04\/7c72b6b957109e063ffe5efe1a1b4673-768x425.jpg 768w\" sizes=\"auto, (max-width: 1096px) 100vw, 1096px\" \/><\/p>\n<h3>Consultas y solicitudes<\/h3>\n<p>\u00a1Hagamos que las maravillas y la diversi\u00f3n de la ciencia est\u00e9n un poco m\u00e1s cerca de todos!
