Existe otra variable a tener en cuenta cuando de la aplicación de un trabajo se trata: el tiempo en que se aplica. Por ejemplo,

en el deporte de carreras de caballos se evidencia un ganador, así como el último en llegar. Si consideramos la misma trayectoria competitiva, podemos afirmar que los dos hicieron el mismo trabajo al llegar a la meta, sin embargo, el caballo ganador lo hizo más rápido. La magnitud física que permite determinar en qué difieren, entre el caballo ganador y el último en llegar, es la potencia. Entonces, ¿intervendrá la potencia muscular de los caballos?, ¿qué implica la magnitud que mide la rapidez con que se realiza un trabajo?, ¿se podrá generalizar a los motores, por ejemplo, de los vehículos? A continuación, los temas desarrollados ayudarán a la comprensión de esta nueva magnitud física.Rapidez para efectuar el trabajo: Sin duda alguna habrás observado en las construcciones el trabajo de las grúas para subir bloques hacia los pisos más altos. Considerando la figura, supongamos que disponemos de dos grúas para levantar bloques de un mismo peso y a la misma altura. En el momento de iniciar el desplazamiento vertical de la carga de bloques, se registra el tiempo y se advierte que la grúa de la izquierda se demoró menos tiempo. ¿Cuál crees que realizó más rápido el trabajo? Evidentemente la grúa de la izquierda. La medida de la rapidez para realizar un trabajo se denomina POTENCIA.
