解题步骤

1. Understand the question

   mission kg2: slope and shape of position-time graphs
   various time intervals during the motion are depicted by a letter on a position-time graph. during which time interval(s) is the object slowing down? select all that apply. if there are no instances of slowing down, then tap the no answer button.

2. Brief Explanations

   Un objeto se ralentiza cuando su velocidad (pendiente de la gráfica posición-tiempo) disminuye en magnitud, es decir, cuando la pendiente se acerca a cero.

   • Intervalo A: La pendiente es negativa y constante (velocidad constante, no se ralentiza).
   • Intervalo B: La pendiente es cero (objeto en reposo, no se ralentiza).
   • Intervalo C: La pendiente es positiva y constante (velocidad constante, no se ralentiza).
   • Intervalo D: La pendiente positiva disminuye hasta llegar a cero (la magnitud de la velocidad disminuye, el objeto se ralentiza).
   • Intervalo E: La pendiente es cero (objeto en reposo, no se ralentiza).
   • Intervalo F: La pendiente negativa aumenta en magnitud (la velocidad se hace más negativa, el objeto acelera en dirección negativa, no se ralentiza).
   • Intervalo G: La pendiente es cero (objeto en reposo, no se ralentiza).
3. Final answer

   D
