To study problems that involve power and efficiency.
To introduce the concept of a conservative force and apply the theorem of conservation of energy to solve kinetic problems.
14.1 The Work of a Force
In this chapter, we will analyze motion of a particle using the concepts of work and energy. The resulting equation will be useful for solving problems that involve force, velocity, and displacement. Before we do this, however, we must first define the work of a force. Specially, a force (F) will do work on a particle only when the particle undergoes a displacement in the direction of the force. For example, if the force (F) in ...
