produced during its motion. It is predicted that the ball should have a constant horizontal speed, which is the horizontal component of initial velocity. There is no horizontal force. Once finding the theoretical period we when can compare it to experimental measured value we found of the period. This means it will always start with the same gravitational potential energy as it starts swinging from the same point, and hence its maximum speed will remain the same for all lengths of the string. Simple harmonic motion, in physics, repetitive movement back and forth through an equilibrium, or central, position, so that the maximum displacement on one side of this position is equal to the maximum displacement on the other side. The mass was displaced about 3 cm from its equilibrium position and released. Many physical systems exhibit simple harmonic motion (assuming no energy loss an oscillating pendulum, the electrons in a wire carrying alternating current, the vibrating particles of the medium in a sound wave, and other assemblages involving relatively small oscillations about a position of stable equilibrium. A curve of mass load versus period squared from the second part of the experiment was plotted and the slope of line was used to calculate the spring constant a second time. Introduction The goal of this experiment was to observe the effect that the size of an object had on the air resistance shown when the object was in motion.

If a mass is attached to a spring and then displaced from its rest position and released, it will oscillate around that rest position in simple harmonic motion. This will then be repeated six times, each time changing the length of the string. I expect that as the length (L) is reduced, the period (T) will decrease as the pendulum will have to cover less distance during each complete swing. With this data we created a sine curve to display the oscillating effect which was made possible by using the translational oscillation.
