A toy train continuously runs along a circular path. Which of the following options correctly explains the type of motion of the train?
As the toy train continuously runs along a circular path with respect to time, so it is in a circular motion.
When the body moves in a straight line with respect to time, it is known as linear motion.
When the body moves about its own axis, it is known as rotational motion.
When the body moves forward and backwards about its mean position with respect to time, it is known as oscillatory motion.
