This is a simulation of a double pendulum. Motion under Different Kinds of Force. Put these simulations in your Public GlowScript folder and share the link with me. That means all of the balls at larger distances would accelerate more slowly than the meter stick. But one thing that will be really worthwhile is an undertaking. Pendulum problems were chosen because they provide fast, difficult-to-observe results and involve straightforward experimentation that may be accomplished with both a physical apparatus and a computer simulation. The apparatus consists of a physical pendu-lum coupled to a drive motor using a pair of springs, a pulley, and string. The period for a simple pendulum does not depend on the mass or the initial anglular displacement, but depends only on the length L of the string and the value of the gravitational field strength g.
