Physics as a knowledge branch about phenomena of nature has many abstract concepts. Due to that fact, physics learning is usually accompanied by laboratory activity. However, there are some physics problems that cannot be simulated in laboratory because of the lack of laboratory equipment. In addition, laboratories are only provided at schools. Therefore, learning media that can help teachers to deliver Physics concepts in more interesting and easy-to-understand way is needed. One of the learning media is simulation on computers. Computers can be used to improve the understanding on more physics materials. With simulation on computers, many physics phenomenon can be learned in detail. Simple and damped harmonic oscillations on springs are quite complex physical systems. Measurements on instantaneous damped quantities, mass and spring constants are very hard to do in a real laboratory. Harmonic oscillation is an object's motion which is periodical along on its equilibrium position. Frictions can make the oscillating motion damped, which is called damped oscillating motion. This research has been done to produce a simulation of simple and damped harmonic oscillation on springs using Delphi 7.0 programming. The simulation of simple harmonic oscillation without damping effect, damped oscillation, oscillation on rough surfaces, and two-way oscillation has been produced. By entering input parameter values, this simulation would give oscillation motion phenomena, which is displayed as moving object visualization, position-time graph, and output parameter related with the oscillating motion. Spring without damping effect will oscillate harmonically. If the damping effect is small, the object will still oscillate but the amplitude decreases exponentially. And if the damping effect is big enough, the object will not oscillate and the spring will only be back to its equilibrium position.
