Unit 1 Description
In this unit, students explore the science of motion - kinematics - by describing and analyzing how objects move. Using a combination of graphical, algebraic, and conceptual approaches, students investigate uniform and non-uniform motion in one and two dimensions. They learn to intepret position-time and velocity-time graphs and to apply equations of motion to solve real-world problems.
Students develop critical thinking and problem-solving skills through hands-on activities, labs, and motion analysis using technology. Kinematics provides a foundation for all subsequent physics units, as students learn to think like physicists: making observations, identifying patterns, and creating mathematical models to describe the natural world.
