Chapter 14 Study Guide

In Chapter 14, kinetics of particle, work and energy, we could summary this chapter explain us about the moving particle based on the principle of energy that involves force (F), velocity (v) and displacement (s). By these kinds of units, we could solve the problems that involve power (P) and efficiency (ε). In this chapter also explained us about conservation of force and theory of conservation of energy due to solve the problems of kinetic energy. While in Chapter 18, kinetics of rigid, work and energy, we could summary this chapter almost got the same explanation by the chapter 14 which was it contain about work of force, kinetic energy, gravitational potential energy, elastic potential energy, conservation of energy and principle of work and energy. If we study deeply about these two chapters, we could get the similarities and differences about the work and energy by the

Kinetics of particle was means the particle that moving freely in the certain displacement and force direction. While the kinetics of rigid body means the moving thing that connected to another thing in the certain angle and force direction. Firstly, in due the work of force by the kinetics of particle that moving along a finite was determined by integration, U=∫_1^2▒〖F cos⁡θ 〗 ds while in work of force by the kinetics of rigid body that moving in a finite angle was determined by the another integration, U=∫_(θ_1)^(θ_2)▒M dθ which it calculated the value of moment. Then, an another different was in Chapter 14, the kinetics of particle was use the original equation to determine its energy, T=1/2 mv^2 while in Chapter 18, the kinetics of particle was use the new derived equation, T=1/2 〖I_IC ω〗^2 which it came from the equation of T=1/2 〖mv_G〗^2+1/2 〖I_G ω〗^2 that was involved the value of angular velocity (ω) and mass center velocity
