Glossary of Key Terms

• Horizontal Spring: A spring oriented horizontally, typically attached to a mass that can move back and forth along a frictionless surface. This system is often used to model simple harmonic motion.
• Energy Graph: A visual representation showing how different forms of energy (e.g., kinetic energy, potential energy, total mechanical energy) change over time or position in a system.
• HTML5 Applet: An interactive program or application written using HTML5, often incorporating JavaScript for dynamic behavior, that can run directly in a web browser without the need for additional plugins.
• Javascript: A programming language commonly used to add interactivity and dynamic features to websites and web applications, including simulations.
• Open Educational Resources (OER): Teaching, learning, and research materials that are freely available online for anyone to use, adapt, and share, often under open licenses.
• Open Source Physics (OSP): A collaborative project focused on creating and sharing computational tools and resources for physics education, often emphasizing interactive simulations and modeling.
• Displacement (x): The change in position of an object from its equilibrium point. In a spring system, it's the distance the mass has moved from its resting position.
• Velocity (v): The rate of change of displacement with respect to time, indicating how fast and in what direction an object is moving.
• Spring Constant (k): A measure of a spring's stiffness; a higher k value indicates a stiffer spring that requires more force to stretch or compress.
• Mass (m): A measure of the amount of matter in an object, which affects its inertia and response to forces.
• Bungee Oscillation: A type of oscillatory motion involving elastic potential energy and gravitational potential energy, similar in principle to a mass-spring system but often in a vertical orientation with a bungee cord.
• Newtonian Mechanics: The branch of classical mechanics that describes the motion of macroscopic objects at non-relativistic speeds using Newton's laws of motion.
• Energy Work Power: A fundamental area of physics dealing with concepts of energy, the ability to do work, and the rate at which work is done (power).
• Initial Position: The starting location of the mass in the simulation at the beginning of its motion.
• Initial Direction: The starting direction of the velocity of the mass in the simulation at the beginning of its motion.
• Simple Harmonic Motion: A type of periodic motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement. An ideal horizontal spring-mass system exhibits simple harmonic motion.
• Kinetic Energy: The energy possessed by an object due to its motion, proportional to its mass and the square of its velocity.
• Potential Energy: The energy stored in an object due to its position or configuration. In a spring system, this is the elastic potential energy stored when the spring is stretched or compressed.
• Total Mechanical Energy: The sum of the kinetic energy and potential energy in a system, which is conserved in the absence of non-conservative forces like friction
