Different forms of Energy

Postby AdamH02 » Fri Jul 12, 2019 10:48 pm

How many different types of energy are there? When breaking an old leaf for instance, why is there a sound as it cracks? Is the sound a form of energy?

Depends on how much detail you want to go into, but if we're speaking broadly, the two main categories are kinetic energy and potential energy.

Kinetic energy is the energy that is released in movement, so if you're walking you're releasing kinetic energy.

On the other hand, potential energy, as the name suggests is energy that is yet to be expended, or energy that is stored. So for example, a ball at the top of the stairs has a lot of potential energy.

If you go into detail though, energy can be grouped into many categories like thermal energy, chemical energy, nuclear energy, sound energy and more.

Could you please explain the more detailed version, where sound energy is expended or other forms of energy are also released etc.

This is a pretty broad question. There are many different types of energy. Thermal, electrical, potential, kinetic, mechanical are all types of energy. They each have their different attributes, however, in terms of defining them as "energy." In other words, there are different factors that affect what defines energy.
