Indicate which of the following options correctly describes the components of acceleration in different types of motion:
at = 0, an = 0. Rectilinear motion at constant speed.
at = 0, an = constant. Uniform circular motion.
at ≠ constant, an ≠ constant. Accelerated circular motion.
an = 0, at = 0. Rectilinear motion at constant speed.
an = 0, at = constant. Rectilinear uniformly accelerated motion.
an ≠ 0 and at ≠ 0. Curvilinear motion.
