Mechanical energy swing because of the work done by the pendulum to oppose these non-conservative forces. That the loss of mechanical energy in a system always resulted in an increase of the system's temperature has been known for a long time, but it was the amateur physicist James Prescott Joule who first experimentally demonstrated how a certain amount of work done against friction resulted in a definite quantity of heat which should be conceived as the random motions of the particles that comprise matter. This equivalence between mechanical energy and heat is especially important when considering colliding objects. In an elastic collision,
Wuhan University of Technology Automotive Polytechnic University. What was more, in 1999, Hubei No.1 Mechanical Industry School and Hubei Energy Economy School were merged into the university. Later in May 2000, it merged with the other two universities mentioned in the beginning and thus formed Wuhan University of Technology. Currently, the university owns 23 academic schools, 9 state key disciplines, 74 Doctoral programs, 135 Master's programs as well as 82 Bachelor's programs. WUT has about 5,570 staff members, including 650 professors, 3 academicians of China Academy of Engineering and 3 academicians of China Academy of Science. Besides, over 36,000 undergraduates, 16000 postgraduates (including Master
