               TYPES OF KINETIC ENERGY.

Electrical energy

Matter is made up of atoms. In these atoms, there are some even small stuff called electrons that are constantly moving. The movement of these electrons depend on how much energy is has. This means every object has potential energy, even though some have more than others.

Humans can force these moving electrons along a path from one place to the other. There are special mediums (materials) called conductors, that carry this energy. Some materials cannot carry energy in this form, and they are called insulators. We generate electrical energy whey we succeed to cause the these electrons to move from one atom to the other, with the use of magnetic forces.

Sound energy

Sound is the movement of energy through substances in longitudinal (compression/rarefaction) waves. 
Sound is produced when a force causes an object or substance to vibrate . The energy is transferred through the substance in a wave. Typically, the energy in sound is far less than other forms of energy.

Sound energy example
Heat (Thermal energy)

Matter is made up of particles or molecules. These molecules move (or vibrate) constantly. A rise in the temperature of matter makes the particles vibrate faster. Thermal energy is what we call energy that comes from the temperature of matter. The hotter the substance, the more its molecules vibrate, and the therefore the higher its thermal energy.

LIGHT ENERGY

Light energy is a type of kinetic energy with the ability to form types of light people can see as well as invisible waves. Light is a form of electromagnetic radiation, and hot objects, such as light bulbs, the sun and lasers, emit it.
WIND ENERGY

Wind is caused by huge convection currents in the Earth's atmosphere, driven by heat energy from the Sun. This means as long as the sun shines, there will be wind.
