Hola nois i noies,<\/p>\n
Aquest tema de les m\u00e0quines no l\u2019hem treballat a classe. No \u00e9s un tema f\u00e0cil d\u2019entendre sense explicar i veure exemples en directe com far\u00edem a classe. Per tant, despr\u00e9s de veure les vostres activitats vull felicitar-vos a tots i totes pel vostre esfor\u00e7.<\/p>\n
Aqu\u00ed teniu l\u2019esquema de les m\u00e0quines. La idea \u00e9s que les m\u00e0quines simples tenen poques peces, mentre que les m\u00e0quines complexes de peces entenen moltes.<\/p>\n
Pel que fa al funcionament de la muntanya russa, primer cal que entengueu no tenen cap motor. Com es mouen tan de pressa llavors?<\/p>\n
\u00c9s mouen tan r\u00e0pid gr\u00e0cies a dues forces.<\/p>\n
La primera for\u00e7a primera l\u2019aconsegueixen gr\u00e0cies a la baixada. Quan el cotxe de la muntanya russa baixa per la pendent agafa velocitat i aix\u00ed supera la pujada.<\/p>\n
Quan m\u00e9s alta estigui la pendent m\u00e9s r\u00e0pid baixar\u00e0 el cotxe.<\/p>\n
Tamb\u00e9 interv\u00e9 la for\u00e7a de la gravetat, que \u00e9s la for\u00e7a com que la Terra atrau els objectes. Si deixen caure una pilota cap avall, aquesta ser\u00e0 atreta per la Terra i la seva velocitat de caiguda ser\u00e0 major quan m\u00e9s alt es deixi caure.<\/p>\n

Aqu\u00ed teniu un v\u00eddeo per a qu\u00e8 experimenteu les forces que intervenen en una muntanya russa.<\/p>\n
