Newton Isaac

in #ita7 years ago
La dinamica della meccanica si occupa dello studio del moto, che possono avvenire in un determinato contesto sperimentale come nella foto in basso.

Legge di gravitazione di Newton.

Secondo Newton, le forze non sono la causa del moto, ma producono una variazione dello stato di moto, ossia un'accelerazione del corpi.
Questa intuizione equivale alla relatività del movimento; dove un osservatore può determinare il suo stato di quiete o di moto solo relativamente ad altri corpi in questo caso tutte le sfere.

Il moto e la causa generata di una posizione di un corpo in funzione nel tempo è stato il primo problema affrontato dalla fisica,i calcoli delle traiettorie e delle forze esercitate dai corpi basati sulle leggi Newtoniane .

Forza del moto detta anche forza d'inerzia mentre nella meccanica classica la posizione di un punto nello spazio è determinata dal vettore posizione definito all'interno di un sistema cartesiano.
Il concetto matematico di vettore nasce dall'idea intuitiva di una grandezza fisica (come ad esempio spostamento, accelerazione e forza)

Cosa che possiamo vedere nel video in atto.

Bel post, in questo esempio la forza d'inerzia, tralasciando gli attriti vari si trasforma in forza potenziale e vice versa.
