Kinetic Energy

Kinetic Energy is energy of motion

The particles in substances gain kinetic energy as they warm, and lose kinetic energy as they cool

Matter expands when the kinetic energy of its particles increases; matter contracts when the kinetic energy of its particles decreases

Particles of substances are always in motion The amount of motion can change

Objects in motion have energy. Energy of motion is called kinetic energy There is a direct relationship between the amount of motion and the amount of kinetic energy

The kinetic energy of particles is heat As the amount of kinetic energy increases, heat increases And vice-versa……..

The amount of heat (particle kinetic energy) can change as a result of energy transfer Energy transfer occurs when particles come in contact with one another
