This is an introductory algebra-based physics course. Emphasis is placed on developing an understanding of motion, forces, energy, momentum, waves, light, electricity, magnetism, and concepts of modern physics.
This course is a one-semester, algebra-based physics course for non-science majors. It introduces basic concepts, theory, and applications of classical mechanics (matter and motion, kinematics and dynamics, waves), thermal physics, electricity, magnetism, light, and modern physics. This course:
1. Introduces basic physics concepts in mechanics, thermodynamics, electromagnetism, and optics
2. Provides students with the fundamental understanding of the principles and laws of classical physics 3. Teaches problem solving techniques
4. Helps to develop analytical thinking
5. Teaches how to apply the physical principles and knowledge to other disciplines
6. Demonstrates how observation, experiment, and theory work together to continue to expand the frontiers of knowledge of the physical Universe.
The emphasis is on improved critical thinking skills, and on developing an ability to approach and solve physics problems.

College Physics I:
Ask most people what they know about physics, and you will probably get an answer like, “it’s hard with lots of math.” That answer, although it has some truth to it, misses the big picture. Physics is the science that uses observation and reasoning to explain why things happen in the real world and how to predict what will happen next.
In this class we will be studying “mechanics”, which explains how and why things move. Mechanics explains why a quarterback who throws a tight spiral has better accuracy than a QB who cannot. It explains why the top rung of a ladder has a warning sticker not to sit or stand there. Mechanics is how your insurance company knows that you were going at least 90 mph when your car hit that tree, even though nobody was there to see it but you and you swear you were only doing 45.
In this course, we will be emphasizing how use reason and similarities to make tough problems simpler before we even do any math. Even though you are not expected to memorize a load of equations, using your brain will be required.
