# PH 2011 - Physics I - Mechanics

3 lecture hours 2 lab hours 4 credits
Course Description
This course is a calculus-based introduction to mechanics. Topics include linear and rotational kinematics and dynamics, work, energy, and momentum. The mathematical level of this course includes the use of vector algebra and elementary applications of differential and integral calculus. The laboratory part of the course emphasizes measurement precision, experimental technique, analysis of data, and report writing. Together with Physics II and Physics III (PH 2021 and PH 2031), this course provides one year of university level physics. No more than 4 credits can be counted in any combination with PH 113 or PH 130. (prereq: one year of high school physics with a grade of B) (coreq: MA 136  or MA 136A )
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
• Use calculus to develop kinematics equations for the position, velocity, and acceleration of an object as a function of time, and use these to solve kinematic problems
• Use Newton’s Second Law of Motion to solve dynamics problems
• Identify forces related to each other through Newton’s Third Law of Motion
• Determine the work done on an object
• Use the Work-Kinetic Energy Theorem to solve problems
• Use the Conservation of Energy Principle and Conservation of Linear Momentum
• Use the gravitational force law to solve dynamics problems
• Relate the gravitational potential energy to the idea of a gravitational field
