# Block and Spring on an Inclined Plane Model

The Block and Spring on an Inclined Plane model shows the dynamics ... (more)

The Block and Spring on an Inclined Plane model shows the dynamics of a mass-spring system sliding on an inclined plane with static and kinetic friction. It is a supplemental simulation for <a href="http://dx.doi.org/10.1119/1.3471936">"Damped oscillations and equilibrium in a mass-spring system subject to sliding friction forces"</a> in the American Journal of Physics 78(11), 1120-1127 (2010) by P. Onorato, D. Mascoli, and A. DeAmbrosis and has been approved by the authors and the American Journal of Physics (AJP) editor. The model displays the numerical solution to the equations of motion and shows how the forces change as the mass slides. Users can set the coefficients of friction and the spring constant. The model plots the position, velocity, and net force on the mass as a function of time as the system evolves and in order to show the asymmetry caused by the change in direction of the frictional force when sliding up and down the incline and the importance of friction in establishing equilibrium. The Block and Spring on an Inclined Plane model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_mech_newton_BlockAndSpringOnInclinedPlane.jar file will run the program if Java is installed. (less)

# Boston University Physics: Connection between Circular and Simple Harmonic Motion Model

This computer model shows the the connection between uniform circular motion and ... (more)

This computer model shows the the connection between uniform circular motion and simple harmonic motion by animating the movement of two spring/mass systems. Users can set amplitude, mass, and spring constant so the blocks have different angular frequencies. As the block/spring system moves, watch what happens to the corresponding circular motion animation. This connection is one way to justify the basic equation of motion for an object experiencing simple harmonic motion. This equation also corresponds to one dimension of uniform circular motion. In this simulation, the author goes beyond the equation to explore the phase angle. There are analogous equations for the velocity and the acceleration as a function of time. The <i>Connection between Circular and Simple Harmonic Motion</i> model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_bu_reference_circle.jar file will run the program if Java is installed. (less)

# Bungee Jump JS Model

The Bungee Jump JavaScript Model is a JavaScript implementation of the Java version of this same model. In this simulation, a bungee jumper is dropped from a tower with a fixed length of bungee cord. The simulation operator can control the height of the tower, the stiffness of the bungee cord (determined by its spring constant k), the unstretched length of the bungee cord and the jumper's mass. The player buttons are the play/pause button, the rewind (to t=0) button and the reset button (resets all parameters to initial values). The operator may optionally display the forces acting on the jumper and a plot of the g-forces versus time. Note that the simulation measures the altitude in terms of the location of his feet, thus he hits the ground if his feet get within his 1.7m of height to the ground. The Bungee Jump JavaScript Model was developed using the Easy Java Simulations (EjsS) version 5. It is distributed as a ready-to-run html page and requires only a browser with JavaScript support. It is also distributed as an ePub. (less)

This interactive homework problem was designed to help students understand how to apply calculations in a system involving a mass hanging from a vertical spring. If the spring is stretched and then released, what is the speed of the block when it returns to its original position for the first time? First, learners will answer conceptual questions designed to encourage critical thinking, then they will use the Conservation of Mechanical Energy method to solve the problem. This resource is part of a larger collection of interactive problems developed by the Illinois Physics Education Research Group. <i>Editor's Note: We recommend this resource to promote deeper understanding of the factors that influence the motion of a mass hanging from a spring. The author anticipates student conceptual roadblocks and helps them recognize how to use alternative problem-solving methods when the kinematic equations would become overly tedious.</i> (less)
