Fuerzas





The Big Bang



Earth evolution (Podéis hacer clic en la siguiente imagen para verla ampliada)





¿Por qué ocurren las estaciones?

 ¿Qué es una fuerza?

En física clásica, la fuerza (abreviatura F) es una magnitud vectorial que modifica el movimiento de un cuerpo (lo acelera, frena, cambia el sentido, etc.) o bien lo deforma. 
Vamos a ver en qué consisten esta definición.

Es una magnitud vectorial:


Deformación : Plástica y elástica.


Cambio de: dirección y/o sentido



Inercia del reposo o del movimiento:

 


Tipos de fuerza: De contacto o a distancia:





Aquí podéis ver un par de vídeos que hemos comentado en clase sobre el electromagnetismo:







Fuerza de rozamiento:











Aquí tenéis dos vídeos, el primero grabado en una misión lunar y el segundo en las instalaciones de la NASA en Cleveland. Con ellos podemos responder preguntas tales como:
¿Qué cae antes una pluma o un martillo?
¿Qué cae antes una bola o una pluma?
