Can an object have a constant speed and still be changing speed? Can you have a variable speed and a constant velocity?

1. \text{No, un objeto no puede tener una rapidez constante y cambiar de velocidad.}

2. \text{No, un objeto no puede tener una rapidez variable y una velocidad constante.}

\text{Respuesta: No y No.}

Explanation in plain words:
1. Because if a speed is constant, the magnitude of the velocity (which is speed) is constant although the direction may change.
2. Because if the speed is variable, it means the magnitude of the velocity is changing.
