Question

Correct the following statement: The motion of a swing is an example of rectilinear motion.

Answer 1

Rectilinear motion:

1. An object is said to be in a rectilinear motion when two objects are moving in a straight line and are parallel to each other.
2. The motion of a train and gravitational forces acting on objects resulting in free fall are some examples of a rectilinear motion.

The motion of a swing:

1. The motion of a swing is an example of periodic motion.
2. Periodic motion is defined as motion that repeats itself at equal intervals of time.
3. A tuning fork or the motion of a pendulum are both examples of periodic motion.
4. If you analyze the motion, you will notice that the pendulum only passes through the mean position after a definite interval of time.
5. The motion described above can also be classified as oscillatory.
6. The swing's back and forth motion makes it periodic.

Hence, the corrected statement is “The motion of a swing is an example of periodic motion”.
