Explanation:

Step1: Analizar gráficas posición - tiempo

En una gráfica posición - tiempo, la pendiente es la velocidad. Una línea horizontal significa velocidad cero (objeto en reposo), una diagonal significa velocidad constante, una curva significa aceleración, una pendiente gradual significa baja velocidad y una pendiente pronunciada significa alta velocidad.

Step2: Resolver preguntas de gráfica posición - tiempo

Identificar objetos en reposo, acelerando, etc. basados en la pendiente y la forma de las curvas.

Step3: Analizar gráficas velocidad - tiempo

En una gráfica velocidad - tiempo, la pendiente es la aceleración y el área bajo la curva es el desplazamiento. Una línea horizontal significa aceleración cero, una diagonal significa aceleración constante, una pendiente gradual significa baja aceleración y una pendiente pronunciada significa alta aceleración.

Step4: Resolver preguntas de gráfica velocidad - tiempo

Identificar objetos en reposo, acelerando, cambiando de dirección, etc. basados en la pendiente y la forma de las curvas.
