Literature relating to the presence of ESL students in mainstream classes has suggested that some teachers view subject-related content mastery and second-language development as separate processes, with the latter seen as the responsibility of ESL-specialist teachers (Penfield, 1987).
Kinetic energy is the production of energy by an object in motion. There are three subcategories of kinetic energy, including vibrational, which is caused by objects vibrating; rotational, which is caused by moving objects; and translational, which is caused by objects hitting one another.
A clear example of this is the fact that water heats up when you put in a water boiler device. Energy has many forms, such as light, heat, electricity, chemical energy (stored in chemical bonds) and mechanical energy (moving matter, such as flowing water). All energy forms are divided up between two main kinds of energy. The first main kind of energy is kinetic energy, the energy of motion and action.
