To express work in a way that is independent of the path taken, a change in a quantity that depends on only the end points is needed. The capacity to do work that a body or system has by viture of is position is called its potential energy. dr = 0 If friction is present, a system is non-conservative.Independence of W12 on the particular path implies that the work done around a closed ciruit is zero:∮ F A force is considered conservative if the work is the same for any physically possible path. dv W12 = m 2 (v22 − v21) = T2 − T1 Kinetic Energy: T = mv2 2 The work is the change in kinetic energy.In most cases, mass is constant and work simplifies to: W12 = m ∫ 2 1 dv dt Torque is the time derivative of angular momentum: 1 T = dL dt. Newton’s second law of motion holds in a reference frame that is inertial or Galilean. In most cases, mass is constant and force is simplified: F = d dt (mv) = m dv dt = ma. ‘Classical’ refers to the con- tradistinction to ‘quantum’ mechanics.
