(4) 3) Select the best answer. Why are the meters squared in the formula to calculate acceleration? The seconds are squared to show exponential acceleration. The seconds are squared to show constant acceleration. The seconds are squared because velocity often has units of meters per second (m/s) and time also has units in seconds (s). The seconds are cubed not squared.

Answer

La respuesta correcta es: **Los segundos están al cuadrado porque la velocidad a menudo tiene unidades de metros por segundo $(m/s)$ y el tiempo también tiene unidades en segundos $(s)$.**<br /><br />La aceleración se define como el cambio de velocidad en un determinado tiempo. La fórmula para la aceleración es:<br /><br />Aceleración = (Cambio de velocidad) / (Tiempo)<br /><br />Si la velocidad se mide en metros por segundo (m/s) y el tiempo en segundos (s), entonces las unidades de aceleración son metros por segundo al cuadrado (m/s²). Esto se debe a que al dividir m/s entre s, matemáticamente resulta en m/s². No tiene que ver con una aceleración exponencial o constante, sino simplemente con las unidades de las magnitudes involucradas en el cálculo. La opción de segundos al cubo es incorrecta.<br />
