Muscular energy is used while writing. Writing involves motion of muscles.
Seismic waves are the forms of energy produced by an earthquake.
Thermal energy is produced.
Solar Energy
When energy changes forms, it is not always produced. In fact, energy is conserved in a system, meaning it can neither be created nor destroyed. So, when it changes forms, the total amount of energy remains constant.
Heat and Light energy
Seismic waves are the forms of energy produced by an earthquake.
Electrical energy
Light
The most common type of energy produced when energy changes forms is heat energy. This is due to the inherent inefficiencies in most energy transformation processes, which result in some of the initial energy being converted into heat.
Sound and kinetic energy
Heat is a waste energy from cars- from the engines and from the brakes.
It produces light
