Chapter 3 Static Equilibrium
Static Equilibrium 3.1 The Important Stuff In this chapter we study a special case of the dynamics of rigid objects covered in the last two chapters. It is the (very important!) special case where the center of mass of the object has no motion and the object is not rotating. 3.1.1 Conditions for Equilibrium of a Rigid Object

Chapter 6 Work, Kinetic Energy and Potential Energy
www2.tntech.eduThe potential energy U(r) also has units of joules in the SI system. When our physics problems involve forces for which we can have a potential energy function, we usually think about the change in potential energy of the objects rather than the work done by these forces. However for non–conservative forces, we must directly calculate

Here is a case (two forces acting on a bar) where the net force is zero, but the forces cause the object to rotate: In order to guarantee static equilibrium, we must have 1) net force = 0 AND 2) net torque = 0

Initially, reactants placed in a container have a faster or slower rate of reaction than the rate of reaction of the products. At equilibrium, the rate of the forward reaction is equal or not equal to the rate of the reverse reaction.
