Inelastic Collisions Study Guide

I. Simulation Overview

The Inelastic Collision JavaScript Simulation Applet HTML5 is an interactive tool designed to visually demonstrate the principles of inelastic collisions in physics. It allows users to manipulate variables and observe the resulting changes in momentum and energy. The simulation is designed to be embedded in webpages and is part of a larger collection of physics simulations provided by Open Educational Resources / Open Source Physics @ Singapore.

II. Key Concepts

• Inelastic Collision: A collision in which kinetic energy is not conserved. Some of the kinetic energy is converted into other forms of energy, such as heat, sound, or deformation of the colliding objects.
• Momentum Conservation: In a closed system, the total momentum before a collision is equal to the total momentum after the collision. This is always true, regardless of whether the collision is elastic or inelastic.
• Kinetic Energy: The energy possessed by an object due to its motion. In inelastic collisions, the total kinetic energy of the system decreases.
• Simulation Parameters: These are the adjustable elements within the simulation, like mass, velocity, and elasticity.
• JavaScript HTML5 Applet: A type of interactive simulation that runs in a web browser without requiring additional plugins.

III. Using the Simulation

1. Access: The simulation can be accessed via the provided URL (https://iwant2study.org/lookangejss/02_newtonianmechanics_3dynamics/ejss_model_inelastic/inelastic_Simulation.xhtml).
2. Controls: The simulation includes various controls such as combo boxes, options, zoom sliders, display checkboxes, and field boxes (for adjusting parameters like a, L, and dt).
3. Interaction: Users can typically adjust the initial conditions of the colliding objects (e.g., mass, velocity) and observe the outcome of the collision.
4. Full Screen: Double-clicking anywhere on the screen toggles full screen mode.
5. Play/Pause/Step/Reset: The simulation has buttons to control the flow of time: to play, pause, step forward one increment, and reset to initial conditions.

IV. Quiz (Short Answer)

1. What is the key difference between an elastic and an inelastic collision?
2. State the law of conservation of momentum and explain its relevance in the context of inelastic collisions.
3. What happens to the total kinetic energy during an inelastic collision? Explain why.
4. List three parameters that you might be able to manipulate within the Inelastic Collision JavaScript Simulation Applet.
5. Explain how you would access the Inelastic Collision JavaScript Simulation Applet.
6. Describe one way to toggle the simulation to full screen.

8. What does the simulation allow users to observe about collisions?
9. Explain what is meant by a Javascript HTML5 Applet.
10. What are some forms of energy that kinetic energy is converted to during an inelastic collision?

V. Quiz Answer Key

1. In an elastic collision, kinetic energy is conserved, while in an inelastic collision, kinetic energy is not conserved and is converted into other forms of energy.
2. The law of conservation of momentum states that the total momentum of a closed system remains constant. This law applies to inelastic collisions, meaning the total momentum before the collision equals the total momentum after the collision.
3. The total kinetic energy decreases during an inelastic collision. This decrease occurs because some of the kinetic energy is converted into other forms of energy such as heat, sound, or deformation.
4. Based on the instructions, parameters to manipulate are mass, velocity, and elasticity.
5. The simulation can be accessed by visiting the URL: https://iwant2study.org/lookangejss/02_newtonianmechanics_3dynamics/ejss_model_inelastic/inelastic_Simulation.xhtml.
6. Double-clicking anywhere on the simulation screen will toggle full screen mode.
7. The "Reset" button returns the simulation to its initial conditions, allowing users to start a new trial with fresh parameters.
8. The simulation allows users to observe the changes in momentum, kinetic energy, and velocity of objects undergoing inelastic collisions.
9. A JavaScript HTML5 Applet is an interactive simulation that runs in a web browser using JavaScript and HTML5, without needing additional plugins.
10. During an inelastic collision, kinetic energy can be converted into heat, sound, deformation of the colliding objects, or other forms of energy.

VII. Glossary of Key Terms

• Inelastic Collision: A collision where kinetic energy is not conserved due to conversion into other forms of energy like heat, sound, or deformation.
• Elastic Collision: A collision where kinetic energy is conserved; objects bounce off each other without any loss of kinetic energy.
• Momentum: A measure of mass in motion, calculated as the product of mass and velocity (p = mv).
• Kinetic Energy: The energy an object possesses due to its motion, calculated as one-half times the mass times the velocity squared (KE = 1/2 mv^2).
• Coefficient of Restitution: A measure of the "bounciness" of a collision; it's the ratio of the final relative velocity to the initial relative velocity between two objects.
• JavaScript: A programming language commonly used to create interactive effects within web browsers.
• HTML5: The latest evolution of the standard HTML markup language; used for structuring and presenting content on the web.
• Applet: A small application designed to run within another application, often a web browser.
• Simulation: A model or representation of a real-world process or system, used to study its behavior and characteristics.
• Open Educational Resources (OER): Teaching, learning, and research materials that are freely available for anyone to use, adapt, and share.
