Work Question

Postby Emma Randolph 1J » Wed Jan 30, 2019 10:33 pm

Does anyone understand what exactly "work" is? I'm confused as to what the difference is between work and energy. Are they the same?

Work and energy are different. Work refers to a way that energy can be transferred by a system to its surroundings. Energy is the capacity of a system to do work.
So if a system can do a lot of work, it possesses a lot of energy.

Although the correlation is very similar, work refers to how the energy could be used/transferred and energy is the ability to do work. So just because a system has a lot of energy, it doesn't mean that work is being done because nothing may change or that energy isn't being used.

To add, I think of Work being the ability to do something. For example, if the piston is moving out, that means the gas (system) is doing work because it is physically pushing the piston out of place.

When I think of work, I think of the amount of energy transferred from one form to another in order to do something. Some keywords that help when determining work are: work being done (positive), does/doing (negative).
