Conservation of Mechanical Energy: Mass on a Vertical Spring|
This is a simulation showing a mass oscillating on the end of a spring. The kinetic energy, gravitational and elastic potential energies are shown in bar graph form.
Adjust the mass and the spring constant, then hit the RUN button. Observe the various forms of energy using the bar graphs.
||Momentum & Energy: Elastic and Inelastic Collisions|
This is a simulation of a collision in one dimension between two masses initially sliding toward each other on a frictionless surface. Explore conservation of energy and momentum, as well as elasticity and relative velocity.
Adjust the initial velocities, masses of the boxes, and elasticity with the sliders. Use the buttons to run, pause, and reset the simulation.
||The Ballistic Pendulum|
This is a simulation of a ballistic pendulum. A ballistic pendulum is a device used to determine the speed of a bullet. Follow the instructions below the simulation window.
||Ballistic Pendulum "Quiz"|
Same as the simulation above, except the initial velocity is not shown - it must be determined by the user.
