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.

A ball is held at rest at the top of a hill. The ball is then released and starts rolling down the hill. At the bottom it reache
Alex17521 [72]

Answer:

Gravitational Potential Energy

Explanation:  

a ball is held rest at the top of hill  

gravitational potential energy will store due to its height  

it.   and  body will start move downward and its potential energy will convert into kinetic energy due to motion of body

at the ground level it will stop and potential energy will became zero and kinetic energy get convert into internal energy due to collisions

Which is likely to be more common in our Galaxy: white dwarfs or black holes? Why?
Nookie1986 [14]

Answer:

White dwarfs are likely to be much more common. The number of stars decreases with increasing mass, and only the most massive stars are likely to complete their lives as black holes. There are many more stars of the masses appropriate for evolution to a white dwarf.

A baseball pitcher throws a ball at 40 ms^-1. if the acceleration is approximately constant over a distance of 2 m, how large is
Reil [10]

We have the equation of motion v^2=u^2+2as, where v i the final velocity, u is the initial velocity, a is the acceleration and s is the displacement

Here final velocity, v = 40m/s

        Initial velocity, u = 0 m/s

        Displacement s = 2 m

Substituting 40^2=0^2+2*a*2\\ \\ a=400m/s^2

So the baseball pitcher accelerates at 400m/s^2 to release a ball at 40 m/s.
