1. The Musical Keyboard Simulator JavaScript Applet is designed to provide an interactive, visual, and auditory learning tool for understanding how musical notes and sounds are produced. It allows users to experiment with amplitude and play notes virtually.
2. The amplitude slider controls the loudness of the sound produced by the simulation. Increasing the amplitude results in a louder sound, while decreasing it makes the sound quieter.
3. Besides clicking on the virtual keys, the simulation allows users to play notes by pressing corresponding buttons on their physical keyboard. This provides an alternative and potentially more familiar input method.
4. The reset button in the Musical Keyboard Simulator returns the simulation to its initial state. This allows users to start fresh and clear any changes they have made to the settings, such as the amplitude.
5. This simulation aligns with OER principles by being freely accessible, modifiable, and redistributable. Its open-source nature allows educators to adapt it to their specific teaching needs without licensing restrictions.
6. A teacher could integrate this simulation into a lesson on sound waves by demonstrating the relationship between amplitude and loudness. Students could experiment with the slider to observe how changes in amplitude affect the sound.

9. This simulation provides students with hands-on experience by allowing them to play notes and adjust amplitude directly. This active participation fosters deeper understanding and engagement compared to passive learning.
10. Kinematics is the study of motion without considering the forces causing it, but is not directly relevant to the Musical Keyboard Simulator. This is primarily about sound, which does not involve force.
