Therefore, the oscillations would have the same time period on Earth and the Moon In an ideal spring-mass system, the load on the spring would just be the added weight. If Abe the initial amplitude then the final amplitude of oscillation is From my understanding, $\frac{dE}{dt} < 0$ because friction causes energy to be lost overtime in the spring mass system. You can determine the period of a sine wave by measuring the horizontal distance between two peaks, or any other identical points between two periods (Figure 3). Let x 0 be the equilibrium position or mean position of mass m when it is left undisturbed. In this case, there is no normal force, and the net effect of the force of gravity is to change In a horizontal spring mass system, mass m is released after being displaced towards right by some distance at t =0 on a frictionless surface.

Wolfgang Christian $\begingroup$ @joshphysics what would be the motion like? For example without friction, would it be a simple harmonic motion? Whereas with friction a dumped oscillation? Furthermore, would there be any difference (in the frictionless plane) between attaching mass 2 to mass one through a spring and attaching It to a wall and letting it go? If you're seeing this message, it means we're having trouble loading external resources on our website. If damping in moderate amounts has little influence on the natural frequency, it may be neglected. Intuition suggests that if the damping force is sufficiently weak the Example : Inverted Spring System < Example : Inverted Spring-Mass with Damping > Now let's look at a simple, but realistic case. A spring generates a force proportional to how far it is stretched (and acting in the opposite direction to the stretch) F spring = −k × stretch If we adjust the coordinate system so that x = 0 corresponds to the spring being unstretched, then the stretch of the spring is simply equal to x. The solution to this differential equation is of the form:. π/2D.
