Drag the weight to the spring and see what happens. You can drag the slider to see how it changes. Natural length is the original length of the spring. Mass eq. is the balance point of the weight. The red button is to pause. Click on the ruler to have access to measure lengths. You can also see the velocity and the acceleration
