    Chapter Outline
    • Newton's First Law of Motion
    • Newton's Second Law of Motion
    • Units of Force
    • Newton's Third Law of Motion
    • What it Means to Do Work
    • What is Work?
    • What is Power?
    • Power

    Upon completion of this module, you will be able to:

    • Explain and apply Newton's first, second, and third laws. (CLO1)(CLO2)(CLO3)
    • Identify various forces in a diagram or problem (CLO2) (CLO3)
    • Translate a free-body diagram into a mathematical representation. (CLO2)(CLO5) 
    • Calculate mass, weight, and force (CLO2)(CLO5)
    • Explain what is meant by normal force. (CLO2)(CLO3)
    • Explain the role that inertial plays in effecting motion (CLO2)(CLO3)
    • Discuss the requirements for and consequences of balanced and unbalanced forces(CLO2) (CLO3)
    • Calculate the net force acting on objects and their resulting accelerations. (CLO2)(CLO5)
    • Identify action-reaction pairs (CLO2)(CLO3)
    • Define and calculate work using appropriate SI units (CLO2)(CLO3)(CLO5)
    • Discuss the components needed for work to occur (CLO2)(CLO3)
    • Define and calculate power based on work and time. (CLO2)(CLO3)(CLO5)  

    To achieve these objectives:

    1. Read and view Module 3: Chapter 3: Force, Work, and Power 
    2. Read Chapter 3: Force, Work, and Power in the Exploring the Physical World: Introductory Physics and Chemistry Pressbook
