Q .14.3 Fig. 14.27 depicts four x-t plots for the linear motion of a particle. Which of the plots represents periodic motion? What is the period of motion (in the case of periodic motion)?
The x-t plots for linear motion of a particle in Fig. 14.27 (b) and (d) represent periodic motion with both having a period of motion of two seconds.
a) This shows a continuously increasing curve, which is not periodic.
b) This graph shows a repeating pattern. It represents periodic motion.
c) This graph does not repeat itself regularly, so it is not periodic.
d) This graph also shows a repeating sinusoidal pattern. It represents periodic motion.
