Answer:
The ability to do work is the basic definition of energy. Energy is required to perform any task.
Nuclear fusion reactions happening on sun are the cause of heat, and sun energy.
Proton is the atomic particle with a positive charge just like the electron with the negative charge.
The objects have the kinetic energy during their motion. So the energy of moving object is kinetic energy.
When the objects interact then the friction between their surfaces produces the heat.
The vibration of molecules and the transfer of vibration to the other molecules is because of conduction. Conduction takes place through the vibration of molecules.
Atomic fusion requires extremely high temperatures to occur, that is why it is called thermonuclear.
