This mobile-friendly digital collection features 11 models that use the accelerometer on a smartphone to detect acceleration and read the direction of the gravitational field g. Scenarios modeled include a block sliding on an inclined plane, horizontal and vertical spring oscillators, a pendulum, and a ball on a moving ring. The "Exploration" section is designed to demonstrate physical concepts and provide reading assignments prior to class. The "Problem" section asks students to demonstrate understanding with less guidance. The "Lecture Demos" are simulations without explanation (for use by educators). Don't miss the "Resources" section for tips on turning your smartphone into a robust piece of data collection.

### Next Generation Science Standards

#### Motion and Stability: Forces and Interactions (HS-PS2)

Students who demonstrate understanding can: (9-12)
• Analyze data to support the claim that Newton's second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration. (HS-PS2-1)

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

Forces and Motion (PS2.A)
• Newton's second law accurately predicts changes in the motion of macroscopic objects. (9-12)
Types of Interactions (PS2.B)
• Newton's law of universal gravitation and Coulomb's law provide the mathematical models to describe and predict the effects of gravitational and electrostatic forces between distant objects. (9-12)
Information Technologies and Instrumentation (PS4.C)
• Multiple technologies based on the understanding of waves and their interactions with matter are part of everyday experiences in the modern world (e.g., medical imaging, communications, scanners) and in scientific research. They are essential tools for producing, transmitting, and capturing signals and for storing and interpreting the information contained in them. (9-12)

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

Analyzing and Interpreting Data (K-12)
• Analyzing data in 9–12 builds on K–8 and progresses to introducing more detailed statistical analysis, the comparison of data sets for consistency, and the use of models to generate and analyze data. (9-12)
• Analyze data using tools, technologies, and/or models (e.g., computational, mathematical) in order to make valid and reliable scientific claims or determine an optimal design solution. (9-12)
Constructing Explanations and Designing Solutions (K-12)
• Constructing explanations and designing solutions in 9–12 builds on K–8 experiences and progresses to explanations and designs that are supported by multiple and independent student-generated sources of evidence consistent with scientific ideas, principles, and theories. (9-12)
• Construct and revise an explanation based on valid and reliable evidence obtained from a variety of sources (including students' own investigations, models, theories, simulations, peer review) and the assumption that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future. (9-12)
Developing and Using Models (K-12)
• Modeling in 9–12 builds on K–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)
• Use a model to predict the relationships between systems or between components of a system. (9-12)
• Use a model to provide mechanistic accounts of phenomena. (9-12)
Using Mathematics and Computational Thinking (5-12)
• Mathematical and computational thinking at the 9–12 level builds on K–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)
• Use mathematical or computational representations of phenomena to describe explanations. (9-12)

#### NGSS Nature of Science Standards (K-12)
