you are asked to contemplate the concepts of oscillation and periodic motion (or periodic behavior). These lead to the definition of a special kind of periodic motion called simple harmonic motion. For now, let's just think about periodicity (1) and oscillations for the following two scenarios. Your answers will not be marked for correctness.
Scenario 1: The motion of the second hand on a clock is:_
a. periodic but not oscillatory (I.e. the hand does not oscillate or undergo oscillations).
b. periodic and also oscillatory.
c. not periodic and not oscillatory.
d. oscillatory but not periodic.
Scenario 2: The motion of a person rocking back and forth on a rocking chair to the beat of a song is:_
a. periodic but not oscillatory.
b. periodic and also oscillatory.
c. not periodic and not oscillatory.
d. oscillatory but not periodic.
Please explain why your answers for the two scenarios are either the same or different. Your answer should include brief definitions of periodic and oscillatory (or oscillations).

Oscillatory motion are motion that involves the repeated forward and backward motion of an object or mater between two position, points or states. An oscillatory motion that repeats itself at a regular interval or cycle is a periodic oscillatory motion. Examples of periodic oscillatory motion includes, a pendulum, the upward and downward motion of a weighted spring or a sine wave

while periodic motion is the repeated movement of an object over a specific period of time. The period is the time for the motion to repeat itself measure in seconds.

The motion of the hand of the clock is periodic as it revolves round every minute, but it is in a clockwise direction hence it is not oscillatory

while the motion f a person rocking back and forth on a rocking chair to the beat of a song is periodic and oscillatory
