Physics 20 Overview:
Physics is the study of matter and energy and their interactions. Through the study of physics,
students are given an opportunity to explore and understand the natural world and to become
aware of the profound influence of physics in their lives.
In Physics 20, students further develop their ability to ask questions, investigate and experiment;
to gather, analyze and assess scientific information; and to test scientific laws and principles and
their applications. Physics, as with all sciences, is an experimental discipline requiring creativity
and imagination.
Students are active learners and will assume increased responsibility for their learning as they
work through the program. A thorough study of physics is required to give students an
understanding that encourages them to make appropriate applications of scientific concepts to
their daily lives and prepares them for future studies in physics
