Oscillatory Motion: Graphical representation of oscillatory motion

The video tutorial guides viewers through a simple experiment to understand oscillatory motion. It begins with an introduction to the materials needed: paper tape, a spring, a holder, a weight, and a pencil. The experiment involves setting up these materials to observe the oscillatory motion of a weight attached to a spring. As the weight is pulled and released, the pencil traces the motion on the paper tape, demonstrating simple harmonic motion. The tutorial concludes by explaining that this motion is the simplest form of oscillatory motion.

What shape does the pencil draw during the experiment?
