A non-calculus survey of physics topics including motion, forces, work, energy, and thermal physics. Facility with algebra and trigonometry will be assumed. Students with secondary school experience in physics and/or mathematics through calculus are strongly urged to take the PHY-271 - PHY-272 sequence. Three lectures weekly. In special circumstances, this course may be taken for 3 credits without lab. Consult instructor. Credit for PHY-231 will not be granted to students who have completed PHY-271.
