Heat.
One form of kinetic energy that is manifested in the random motions of atoms and molecules is thermal energy. This energy arises from the movement of particles at the microscopic level, contributing to the overall temperature of a system.
The tempertaure scale that is based on the actual kinetic energy of the molecules is
It could have kinetic energy when the strings are being pulled and it is in operation
All gases have same kinetic energy of molecules at same conditions.
Temperature measures the average kinetic energy of air molecules. As the temperature increases, the molecules move faster and have higher kinetic energy.
'kinetic energy of molecules' is heat; so your answer is any heat engine: for example, a steam locomotive.
temperature is the average kinetic energy of a particle
The measure of the average kinetic energy of a group of molecules is expressed as temperature. As temperature increases, molecules move faster and their kinetic energy increases. This average kinetic energy is directly related to the temperature of the system.
Heating increase the kinetic energy.
Molecules have the most kinetic energy at higher temperatures when they are moving faster. This is because temperature is directly proportional to the average kinetic energy of molecules in a substance.
The kinetic energy of molecules is directly related to their physical state. In general, molecules in a higher energy state (higher kinetic energy) tend to be in the gaseous state, where they have more freedom to move around. Conversely, molecules in a lower energy state (lower kinetic energy) tend to be in the solid or liquid state, where they have less freedom of movement.
