Course Structure and Expectations
Lectures: Focus on conceptual understanding, problem-solving, and group activities.
Pre-lecture reading quizzes: Assess understanding of assigned readings before class.
In-class quizzes: Short assessments during lectures to reinforce key concepts.
Exams: Evaluate mastery of course material; may include multiple-choice and problem-solving questions.
Assignments: Online homework via MyLab and Mastering platform; e-textbook access required.
Group work: Collaboration with peers and Learning Assistants to solve problems and discuss concepts.
Key Definitions and Concepts
Scaling: The study of how physical properties (such as area, volume, and strength) change as the size of an object changes. Example: The surface area to volume ratio is critical in understanding heat loss in animals.
Kinematics: The branch of mechanics that describes the motion of objects without considering the causes of motion. Key equations:
Displacement:
Velocity:
Newton's Laws of Motion:
First Law (Inertia): An object remains at rest or in uniform motion unless acted upon by a net external force.
Second Law: The net force on an object is equal to its mass times its acceleration:
Third Law: For every action, there is an equal and opposite reaction.
Momentum: The product of an object's mass and velocity. Formula:
Work and Energy: Work is done when a force causes displacement. Formula: Energy is the capacity to do work. Formula for kinetic energy:
Simple Harmonic Motion: Periodic motion where the restoring force is proportional to displacement. Formula for period:
Fluids: Substances that flow and take the shape of their container. Key concepts: Pressure (), buoyancy, Bernoulli's principle.
Course Policies and Procedures
Attendance: Regular attendance is expected for both lectures and recitations.
Academic Integrity: Collaboration is encouraged, but all submitted work must be your own. Plagiarism and cheating are strictly prohibited.
Technology: Bring a web-enabled device to class for interactive activities. Cell phones must be silenced and put away during class.
Accommodations: Contact the instructor for any required accommodations or support.
Communication: Check Brightspace regularly for updates, assignments, and announcements.
Assessment Components
Pre-lecture quizzes (based on assigned readings)
In-class quizzes (concept checks and problem-solving)
Exams (midterm and final)
Online homework (MyLab and Mastering platform)
Example Applications
Biomechanics: Applying Newton's laws to analyze human movement and forces in muscles and bones.
Fluid dynamics: Understanding blood flow in arteries and veins using principles of pressure and flow.
Oscillations: Modeling the vibration of vocal cords or the beating of the heart as simple harmonic motion.
