What motion causes thermal energy?
i think is "Matter is made up of atoms and molecules (groupings of atoms) and energy causes the atoms and molecules to always be in motion - either bumping into each other or vibrating back and forth. The motion of atoms and molecules creates a form of energy called heat or thermal energy which is present in all matter."
The motion that causes thermal energy is known as thermal motion. It refers to the random movement of particles in a substance, such as atoms or molecules. This motion can be explained using the kinetic theory of matter, which states that all particles in a substance are constantly in motion.
When a substance is heated, its particles gain energy and begin to move more vigorously. This increase in energy causes the particles to vibrate, rotate, and translate (move in a straight line). As the particles move, they collide with each other, transferring energy between them. These collisions and movements contribute to the overall thermal energy of the substance.
In summary, thermal energy is caused by the random motion of particles within a substance, as they vibrate, rotate, and translate due to the transfer of energy when the substance is heated.
