Lesson 7Kinetics: Work-Energy #1Fall 08 Student Advice: “Don't use the solutions <manual> to the homework; Do the problems consistently throughout the week.”
Admin•Homework #3 Due Friday•Online quiz tonight
Review•Kinematics – (e.g., ads=vdv)•Newton’s second law, FBD and MAD•Path (normal/tangential)•Polar (radial/transverse)
Lesson Objectives1.Derive the work-energy equation from Newton’s second law.1.Understand definitions of work and energy and how to calculate work.2.Calculate the power generated by individual and sums of forces on a particle.3.Apply work-energy relationships to solve dynamics problems.
