Trabajo y energía I: conceptos - Física Los conceptos de trabajo y energía son conceptos complicados de entender. El trabajo se simboliza como W (work en inglés). Este es la fuerza que necesitamos entregarle a un objeto para moverlo de un lado a otro: W = Fuerza por distancia. La energía es la forma en la que el objeto recibe el trabajo. Se habla de dos tipos de energías: Cinética: Tiene que ver con el movimiento Potencial gravitatoria Si tenemos un cuerpo y lo queremos mover debemos hacer una fuerza. La aceleración depende de la fuerza entregada y de la masa. La energía potencial gravitatoria depende de la ubicación del cuerpo.
