Oscillating Crimson: Where Art Meets PhysicsHasini GujjariAward: Top 100
School: massachusetts academy of math and science at wpi This piece of art is known as a pendulum painting. It primarily relates to concepts of simple harmonic motion and gravity, as the painting is created by the swinging motion of a pendulum. A cup of paint is attached to a string and, after the initial push, it begins to oscillate, tracing harmonic paths on the canvas below. When the pendulum swings, it follows a curved, sometimes elliptical or circular path, which is often determined by the string length, the force of gravity, and the initial push force. Additionally, the frequency and amplitude of the motion influence the overall oscillatory pattern; a longer pendulum moves more slowly, while a shorter one oscillates faster. As the pendulum swings, gravitational potential energy is also converted into kinetic energy and back again with the max kinetic energy always occurring in equilibrium. At the endpoints of the swing, the motion slows as the energy shifts back into potential form. Over time, air resistance and friction act on the system, gradually reducing its energy. This leads to damped motion, where the pendulum slows down and the arcs become smaller and tighter toward the center of the canvas – as seen by the thicker lines. Furthermore, this art also resembles Lissajous figures-- which are intricate looping patterns that occur when a pendulum moves in two perpendicular directions at different frequencies. Overall, by combining art and creativity with scientific principles, the pendulum painting consists of beautiful painted complex patterns that represent simple harmonic motion.
