Answer: thermal energy
Explanation: Thermal energy is the conversion of kinetic energy
When potential energy is converted into Kinetic energy, some of that kinetic energy is always in the form of thermal heat energy.therefore the correct option is C.
The sum of all the energy in motion (total kinetic energy) and all the energy that is stored in the system (total potential energy) is known as mechanical energy.
The expression for total mechanical energy can be given as follows
ME= PE + KE
Because all the kinetic and potential energy that is present in the system is added together to form total mechanical energy. Any object or body that moves at any speed has kinetic energy inherent to it; nevertheless, some of this kinetic energy is constantly transformed into thermal energy due to friction.
Hence, we can say that when potential energy is converted into kinetic energy some amount of kinetic energy is always converted into thermal heat energy,therefore the correct option is C.
