37239 Lecture Notes - Net Force
Document Summary
The work-energy theorem is a fundamental principle in physics that relates the work done on an object to the change in its kinetic energy. This theorem can be applied to a variety of situations, including the motion of a particle or a system of particles. The work-energy theorem states that the net work done on an object is equal to the change in its kinetic energy. Wnet = k where wnet is the net work done on the object, and k is the change in its kinetic energy. Work is defined as the product of the force acting on an object and the distance over which the force is applied. W = fd where w is the work done, f is the force applied, and d is the distance over which the force is applied. Kinetic energy is the energy that an object possesses due to its motion, and it is given by the equation:
