### Application and Practice Questions

Lesson 2 has thus far focused on how to analyze motion situations using the work and energy relationship. The relationship could be summarized by the following statements:. There is a relationship between work and mechanical energy change. Whenever work is done upon an object by an external or nonconservative force , there will be a change in the total mechanical energy of the object. If only internal forces are doing work no work done by external forces , there is no change in total mechanical energy; the total mechanical energy is said to be "conserved. Now an effort will be made to apply this relationship to a variety of motion scenarios in order to test our understanding. Use your understanding of the work-energy theorem to answer the following questions.
