height - the vertical dimension of extension; distance from the base of something to the top. tallness. dimension - the magnitude of something in a particular direction (especially length or width or height) loftiness, highness - the quality of being high or lofty.
â¢ Mechanical energy is the ordered movement of the molecules as a single unit. Thermal energy is the random movement of the molecules. â¢ Mechanical energy can be 100% converted to thermal energy, but thermal energy cannot be fully converted to mechanical energy. â¢ Thermal energy cannot do work, but mechanical energy can do work. â¢ Mechanical energy has two main forms, namely kinetic energy and potential energy.
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.For example, a cup of hot tea has thermal energy in the form of kinetic energy from its vibrating particles.When you pour some milk into your hot tea, some of this energy is transferred from the hot tea to the particles in the cold milk.or example, a cup of hot tea has thermal energy in the form of kinetic energy from its vibrating particles.
