Understanding the solutions in this chapter is essential for mastering core engineering principles used in mechanical, aerospace, and civil engineering. Overview of Chapter 13: Kinetics of Particles
You can access step-by-step solutions and problem sets via the following platforms:
In fact, one could argue that the real Chapter 13 is only learned when a student compares their attempted solution to the manual’s and asks: “Why did they choose conservation of energy here while I used Newton’s laws?” That moment of method comparison is the genuine pedagogical event.
must be broken down into scalar components. The 12th edition solutions manual organizes answers based on the most efficient coordinate system for the given problem geometry. 3. Newton's Law of Gravitation

) by drawing its components along your chosen coordinate axes. Set the FBD visually equal to the KD ( Step 3: Apply the Equations of Motion
Kinetics relates the forces acting on a body to its mass and acceleration. Chapter 13 approaches this relationship through Isaac Newton's Second Law (
): Used for linear motion or when forces are easily broken into horizontal and vertical components. Tangential and Normal Coordinates ( The 12th edition solutions manual organizes answers based
For engineering students, by Beer, Johnston, Mazurek, and Cornwell is a pivotal turning point. While previous chapters focus on kinematics (the geometry of motion), Chapter 13 introduces Kinetics of Particles , specifically focusing on Newton’s Second Law .
is an essential academic resource for engineering students mastering the fundamentals of particle kinetics using Newton's Second Law. Chapter 13 focuses on Kinetics of Particles: Newton's Second Law , bridging the gap between pure kinematics (the study of motion without regard to its cause) and the forces that create that motion.
Before looking at the math, look at which coordinate system (
Write out the cable length equation to find dependent motion relationships (e.g., ∑Fr=mar=m(r̈−rθ̇2)sum of cap F sub r equals m
Used for problems relating . The Principle:
Applying Newton's second law in various coordinate systems (Rectangular, Tangential/Normal, and Polar coordinates).
The acceleration is:
If you get stuck, look only at the FBD in the solutions manual. Hide the mathematical steps, and try to finish the problem using their diagram.
