Energy conversion takes place when one form of energy is converted to another form. An example would a turbine, which converts heat energy to mechanical energy, or a generator which converts mechanical energy to electrical energy, or an electric motor which converts electrical energy to mechanical energy.
In all conversion processes energy is lost (i.e. it is converted to heat at a low temperature). The useful power output of a machine is always less than the power input, by a ratio called the efficiency, usually expressed as a percentage. Typical efficiency for an electric motor is 95%, for a car engine 25%.

ReneWhen an energy conversion is happening, the original form of energy is transformed into a different form. This can result in the creation of various types of energy, such as kinetic energy, potential energy, thermal energy, or electrical energy, depending on the specific conversion process.

Hands moving on a battery operated clock is an example of what kind of energy conversion?
Kinetic energy being converted to chemical potential energy
What kind of energy always has a small amount of this energy present at the end of the conversion?
In any energy conversion process, some of the original energy is always lost as heat energy. This heat energy is often a byproduct of the conversion process and cannot be fully utilized to perform work.
Lighting a macth is an example of what kind of energy conversion?
Lighting a match involves the conversion of chemical energy stored in the match head into thermal energy and light energy through the process of combustion.
An avalanche demonstrates what kind of energy conversion?
Gravitational potential energy to kinetic energy
What kind of energy conversion happens when you rub your hands together?
Mechanical energy is converted into thermal energy when you rub your hands together. The friction between your hands causes them to generate heat, which warms them up.
