Give three real-world examples of oscillatory motion. (Note that circular motion is similar to, but not the same as oscillatory motion.)

To illustrate: Three real-world examples of oscillatory motion.
Answer to Problem 1CQ
Three real-world examples of oscillatory motion are given.
Explanation of Solution
The repetitive, back and forth motion of an object about its mean position is regarded as oscillatory motion.
Three real-time examples of oscillatory motion are as follows:
- The mass-spring system, which is basically a spring with a hanging mass. When a mass is hanged to a spring, it moves in an upward and downward direction continuously about its mean position and hence it is an example of oscillatory motion.
- When the tennis ball is stricken, the motion of a tennis ball is an example of oscillatory motion.
- Other examples of oscillatory motion are road bumps of washboard, a swinging pendulum, an AC voltage wave, and a beating heart.
Conclusion:
Thus, three real-world examples of oscillatory motion are given.
