Mechanics and Fluids

UNITS:4
GRADING:Letter or Credit/No Credit
LEVEL:Undergrad
GER:WAY-SMA

How are the motions of solids and liquids determined by the laws of physics? Students learn to describe the motion of objects (kinematics) and understand why objects move as they do (dynamics). Emphasis on applying Newton's laws to solids and liquids to describe diverse phenomena. Everyday examples are analyzed using tools of algebra and trigonometry. Problem-solving skills are developed, including verifying that derived results satisfy criteria for correctness, such as dimensional consistency and expected behavior in limiting cases. Physical understanding fostered by peer interaction and interactive group problem solving. Prerequisite: high school algebra and trigonometry; calculus not required.
