Springs'nThings Lite - Version 1.5 Both Physics and FunSprings ‘n Things is an entertaining demonstration application and educational display for the iPhone/iPad. It simulates the dynamics of up to four springs connected to a moveable ball. Touch, drag and release the ball to see it bounce around. The length and stiffness of the springs can be individually adjusted. One of the springs can be transformed into a fixed spring or a pendulum. The ball can be made to respond to the tilting and shaking motions of the iPhone/iPad. The motion of the ball can be perpetual or it can be slowed by spring resistance by viscous damping as if it were moving in air or water.
