Oscillatory and Random Motion | Motion | Physics

The apparatus seen in this video is a simple frame from which a metallic ball is suspended and set into oscillatory motion. This predictable, uniform motion is compared to the movement of polystyrene/thermocol balls in a forceful stream of air. The video defines oscillatory motion as being steady, repetitive, and therefore predictable whereas the movement of the balls to be random and impossible to predict. Some basic aspects of oscillatory motion, such as movement around a central point and the pause and reversal that happens at the extremes, are observed. The video invites the viewer to think about the motion of a plucked guitar string, and a swing, and designate the type of motion.

Thank you sir for your video it helped me a lot in my physics homework
