October 18, 2010 ABSTRACT.  The core viewpoint of this experiment is to illustrate how work, energy and power are interrelated to each  other. A fan cart, smart timer, and a track were used in order to define work and power as well as the energy conservation   principle. Computation was also done on the work of a motion along a curved path produced. Initial measurement of force   and recording of displacement and time were two primary steps for obtaining work and power. When the fan cart moves at  a longer distance, it produces a greater amount of work. On the other hand, since the object is moving horizontally, the   power is remained  constant. Afterwards, work and  energy (gravitation  potential energy)  was obtained  on a  much   complicated means because it displaces on a curve path. Continual increase in pulling the object is done in order to raise   it at a certain height.  Later in that, it is found out that potential energy and work are of the same magnitude which can be   proven by the law of conservation of energy and work-energy theorem. INTRODUCTION Aircrafts do normally take off from the deck of ships  through   catapult   system   (catapult   –   mechanism   for  launching aircraft at a speed sufficient for flight). Large  force is applied to the aircraft as it is displaced across  the deck of a ship. Obviously, the purpose of this is to  attain   a   certain   speed   before  it   can   remain   airborne  which   the   catapult   provides.   In   the   language   of  kinematics, it is described as the motion of the plane  having accelerated. In the language of Newton’s law, it  can be explained as the net force of the object is causing  it to accelerate. Nonetheless, another language can be  used   by   physicist   to   explain   this   phenomenon.   It   is  through the concept of work and energy. This experiment  intended to explain how work, energy and power are  different and how they are related as well. One vital concept of physics is the energy. The universe
