In this unit, students will begin the course by exploring how physicists investigate the natural world through observation, experimentation, and mathematical modeling. They will learn the importance of accurate measurement, precision, uncertainty, and data analysis while developing the skills needed to design controlled investigations and communicate scientific findings. By establishing a strong foundation in the science and engineering practices, students will gain the tools necessary to think critically, evaluate evidence, and construct models that explain physical phenomena.
In this unit, students will investigate how objects move by analyzing position, velocity, acceleration, and time using graphs, equations, and vector representations. Through laboratory investigations and mathematical modeling, they will discover patterns in one-dimensional and two-dimensional motion, including projectile motion and free fall. Students will develop predictive models that allow them to describe and explain motion without considering the forces that cause it, emphasizing the role of mathematics as a language for understanding the physical world.
In this unit, students will build upon their understanding of motion. Students will examine the interactions that cause objects to accelerate. They will apply Newton's three laws of motion to analyze balanced and unbalanced forces, friction, tension, and systems of objects using free-body diagrams and quantitative reasoning. Through engineering challenges and experimental investigations, students will explain how forces govern everyday experiences ranging from vehicle safety to athletic performance while recognizing that interactions between objects are fundamental to changes in motion.
In this unit, students will explore the concept of energy as a conserved quantity that can be transferred and transformed but not created or destroyed. They will investigate the relationships among work, kinetic energy, potential energy, power, and efficiency through laboratory experiments and real-world applications. By analyzing systems such as roller coasters, pendulums, and mechanical devices, students will develop models that explain how energy conservation provides a powerful framework for predicting physical behavior across a wide range of phenomena.
In this unit, students will study momentum as another conserved quantity that describes the motion of interacting objects. Through investigations of collisions, explosions, and impulse, they will analyze how forces acting over time produce changes in momentum and how conservation principles can predict the outcomes of interactions. Engineering applications such as vehicle safety systems and protective equipment demonstrate how understanding momentum and impulse can be used to reduce injury and improve technology through informed design.
In this unit, students will examine the forces responsible for circular motion and planetary orbits by connecting Newton's laws with universal gravitation. They will investigate how centripetal forces maintain circular paths and how gravitational interactions govern the motion of satellites, planets, and galaxies. Using mathematical models and simulations, students will discover that the same physical laws describing objects on Earth also explain the large-scale structure and motion of the universe, illustrating the unifying nature of physics.
In this unit, students will investigate waves as mechanisms for transferring energy and information without transferring matter. They will explore wave properties such as frequency, wavelength, amplitude, and speed while examining phenomena including interference, resonance, standing waves, and sound. Through experimentation and modeling, students will explain how wave behavior accounts for technologies ranging from musical instruments to medical imaging and communication systems, highlighting the universal principles that govern wave interactions.
In this unit, students will explore the behavior of electric charges and magnetic fields to understand the principles underlying modern technology. Through constructing circuits, measuring electrical quantities, and investigating electromagnetic interactions, they develop models explaining current flow, resistance, energy transfer, and induction. Students will discover how the relationship between electricity and magnetism enables power generation, electronic devices, communication systems, and countless engineering innovations that shape contemporary society.
