"General physics is the foundation that permits us to study large and small systems, such as galaxies and nanostructures, or car crashes and atomic interactions."

WHAT IS PHYSICS ANYWAY?

Physics is an in-depth study of how objects interact with each other. These objects can be macroscopic; large enough to be seen without a microscope, or microscopic; small enough that you need a microscope or some other means to identify them. The laws of physics are used to predict and/or confirm how objects behave when at rest or in motion.

Important things to know

Units

Units are particular physical quantities, defined and adopted by convention, with which other particular quantities of the same kind are compared to express their value. The metric system of units is the global standard, except for in the United States.

Vectors

Vectors are a way to quantify magnitude and direction. Examples of vector applications are wind speed and direction, driving, riding an elevator or pushing a crate. Understanding vectors is an important part of physics, as they are present in many subtopics.

Vector Operations

Most mathematical operations used with numbers also apply to vectors. Vectors may be added, subtracted and even multiplied. Vectors are commonly deconstructed into components along 2 or 3 dimensions in order to easily manipulate them.

The Vector Trigonometry course provides essential information that is required for calculating x, y and z components of vectors. Mastering the concepts and application of these concepts are key parts of each section as Introductory Physics I progresses.

Dr. Trina L. Coleman

Dr. Coleman has taught STEM courses for over 20 years and is passionate regarding the recently trending interest in exposing underrepresented students to STEM (Science, Technology, Engineering and Mathematics) programs. Her site, academicblueblood.com, is a playbook for partnering STEM mentors and organizations with students interested in STEM for the long haul. She holds a Ph.D. in Nuclear Theory from Hampton University.
