Sabeu per qu\u00e8, tant nosaltres com tots els objectes comuns es mantenen subjectes a terra en comptes de surar o sortir disparats?\u00a0<\/span><\/p>\n

Aix\u00ed \u00e9s com va comen\u00e7ar el nostre experiment del dijous 23 de maig per demostrar el concepte de Gravetat.\u00a0<\/span><\/p>\n

El nostre company Gino de cinqu\u00e8 ens va fer tres experiments amb materials molt senzills (una ploma, una bala, dues carmanyoles i un mocador), per\u00f2 no era possible demostrar la llei de gravetat sense parlar d’en <\/span>Galileu. u<\/b>n gran astr\u00f2nom, f\u00edsic, mec\u00e0nic, fil\u00f2sof i matem\u00e0tic.<\/span><\/p>\n

Per entendre que en el moviment (i la caiguda) dels cossos no nom\u00e9s influeix la gravetat, vam provar de deixar caure des de la mateixa altura una ploma i una bala.\u00a0<\/span><\/p>\n

Aix\u00f2 ens va demostrar que aquest fet es produeix, no perqu\u00e8 la pedra pesi m\u00e9s que la ploma, sin\u00f3 perqu\u00e8 la ploma exerceix una resist\u00e8ncia a l’aire molt m\u00e9s gran que la pedra a causa de la seva forma. \u00c9s a dir, tenen diferent fricci\u00f3 amb l\u2019aire.<\/span><\/p>\n

Despr\u00e9s vam fer el mateix posant aquests objectes dins de dues carmanyoles iguals. I vam observar que\u00a0 ambd\u00f3s objectes cauen a la mateixa velocitat dins de les carmanyoles. Per tant, aqu\u00ed vam entendre que, tot i tenir diferent massa, ara hi havia la mateixa fricci\u00f3 i, per tant, quien alhora.<\/span><\/p>\n

Per acabar d\u2019entendre aquest concepte en Gino ens va fer un tercer experiment relacionant la gravetat amb la for\u00e7a d\u2019atracci\u00f3 relacionada amb el moviment planetari.<\/span><\/p>\n

I gr\u00e0cies en aquest \u00faltim experiment vam entendre que la caiguda no dep\u00e8n de la massa de l’objecte en caiguda, sin\u00f3 que dep\u00e8n de la resist\u00e8ncia amb l\u2019aire.<\/span><\/p>\n

Aprenem tots junts mitjan\u00e7ant la ci\u00e8ncia!<\/span><\/p>\n

Gr\u00e0cies Gino!<\/span><\/p>\n
