In this lecture, we will revisit the principle of work and energy introduced in lecture D7 for particle dynamics, and extend it to 2D rigid body dynamics. Kinetic Energy for a 2D Rigid Body We start by recalling the kinetic energy expression for a system of particles derived in lecture D17

Chapter One Introduction Heat: Heat is a kind of energy, Which occurs in the transfer process. (the transferred energy contains the orderly work and disorderly heat) Energy: Concept of energy is used to specify the state of a system in thermodynamics Heat Transfer: kind of application science, is concerned with analysis of the rate of heat transfer taking place in system, or with the research on the heat-transfer reqularity

Chap. 14: Energy in Thermal Processes Solids, liquids or gases have internal energy t Kinetic energy from random motion of molecules translation rotation vibration
