LEARNING ACTIVITIES ON MECHANICAL ENERGY

Preface These Learning Activities on Mechanical Energy in Cebuano-English is conceptualized and designed to help both the teachers and students in bridging the gap between science and language. For places where English is only a second or third language, such as in the Province of Bohol, learning science, particularly Physics, is hindered by a language barrier. Most scientific terms have different operational definitions. These English scientific terms have different meanings when used in everyday language. This problem is compounded especially for those terms where no Cebuano equivalent can be found. Furthermore, there are several English scientific terms, which have only one Cebuano equivalent. A very appropriate example is “kusóg” which is the Cebuano translation for the following English words: energy, force, power, fast, stamina, vigor, and vitality. Note that the first three words listed are also used as scientific terms. In fact, these three terms are very important Physics concepts in Mechanical Energy.

INTRODUCTION
Energy (enerhiya o kabaskog) is perhaps the concept most central to all of Physics and science. The combination of energy and matter makes up the universe: as matter is substance, and energy is the mover of substance. The idea of matter is easy to grasp (Hewitt, 1993). Energy, on the other hand, is an abstract and difficult concept. (Lisod sabton ang enerhiya kay dili man kini makita.) For most students, this concept needs to be made visible and should be linked to everyday experiences.

An abstract definition such as “energy is the capacity to do work” does not create much understanding on the part of the students and the statement is even false as soon as other forms of energy are discussed (van den Berg and Grosheide, 1998) in class. (Sa Physics, ang enerhiya ang hinungdan nga kita maka trabaho. Pero kon imong pagabatbaton ang laing-laing porma sa enerhiya, dili na...
