Engineering Mechanics
Engineering Mechanics. Instructor: Professor Manoj K Harbola, Department of Physics, IIT Kanpur. In this course, we would be studying mechanical interaction between different bodies when they interact through the forces applied on each other. Topics covered in this course include Review of Newton's laws of motion and vector algebra; Equilibrium of bodies; Plane trusses; Friction; Properties of plane surfaces; Method of virtual work; Motion of particles; Momentum; Work and energy; Rotational kinematics and dynamics; Simple harmonic oscillator; and Motion in non-inertial frames.

| Lecture 55 - Definition of Potential Energy for Conservative Forces; Total Mechanical Energy and ... |
In the previous lecture we defined conservative force fields as those where the work done by the field between two points is independent of the path. For such fields, therefore, the work done can be written as a quantity dependent only on the end points. Using this fact, in this lecture we define the potential energy for a force field and by applying the work-energy theorem with it, obtain the principle of conservation of energy.
