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.
Kinetic energy is energy possessed by an object in motion. The earth revolving around the sun, you walking down the street, and molecules moving in space all have kinetic energy. Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
