Masses and springs
This online resource is a simulator that allows students to study the effect on springs of falling masses under various conditions.
Different masses can be added to up to 3 springs and their stiffness and damping can be adjusted.
The springs are extended and released and their motion can be analysed via energy graphs which show kinetic, potential, thermal and total energy.
Sample learning goals, along with many downloadable documents of teaching ideas, are also available on the site and link from this activity.
This Flash-based resource will not work on the Apple iPad.
Registration is needed to access all aspects of the site. This is free, but a donation is suggested.
