## Detail Page

This interactive simulation lets students investigate simple collisions in one dimension or more complex scenarios. The simpler experiment explores the meaning of elastic vs. inelastic collisions, while the 2D model integrates the Law of Conservation of Momentum to solve problems. Users can adjust the mass of the two balls and set the elasticity from zero to 100%. The website also provides lesson plans developed by high school teachers specifically to accompany the Collision Lab simulation.

### Next Generation Science Standards

#### Disciplinary Core Ideas (K-12)

Forces and Motion (PS2.A)
• Momentum is defined for a particular frame of reference; it is the mass times the velocity of the object. (9-12)

#### Crosscutting Concepts (K-12)

Systems and System Models (K-12)
• When investigating or describing a system, the boundaries and initial conditions of the system need to be defined and their inputs and outputs analyzed and described using models. (9-12)

#### NGSS Science and Engineering Practices (K-12)

Developing and Using Models (K-12)
• Modeling in 9â12 builds on Kâ8 and progresses to using, synthesizing, and developing models to predict and show relationships among variables between systems and their components in the natural and designed worlds. (9-12)
• Develop and use a model based on evidence to illustrate the relationships between systems or between components of a system. (9-12)
Using Mathematics and Computational Thinking (5-12)
• Mathematical and computational thinking at the 9â12 level builds on Kâ8 and progresses to using algebraic thinking and analysis, a range of linear and nonlinear functions including trigonometric functions, exponentials and logarithms, and computational tools for statistical analysis to analyze, represent, and model data. Simple computational simulations are created and used based on mathematical models of basic assumptions. (9-12)
• Create a computational model or simulation of a phenomenon, designed device, process, or system. (9-12)

### AAAS Benchmark Alignments (2008 Version)

#### 4. The Physical Setting

4F. Motion
• 9-12: 4F/H2. All motion is relative to whatever frame of reference is chosen, for there is no motionless frame from which to judge all motion.
• 9-12: 4F/H4. Whenever one thing exerts a force on another, an equal amount of force is exerted back on it.
• 9-12: 4F/H8. Any object maintains a constant speed and direction of motion unless an unbalanced outside force acts on it.

#### 11. Common Themes

11B. Models
• 9-12: 11B/H1a. A mathematical model uses rules and relationships to describe and predict objects and events in the real world.
